msPs ====================================================================== Supplementary Notes The RA, dec and most of the elements listed for V1-410 in the above table are from the catalogue published by Kaluzny et al. (2004). In cases where they adopted the periods, magnitudes, amplitudes and classification from other sources because the stars' images were saturated on their frames or if they were outside their field of view, this is indicated in the remarks column where the source is indicated as follows: Bai refers to Bailey (1902) Mar refers to Martin (1938) vG refers to van Gent (1948) Fea refers to Feast (1965) Wil refers to Wilkens (1965) DC refers to Dickens & Carey (1967) DFL refers to Dickens et al. (1972) Eg refers to Eggen (1970) GSz refers to Geyer & Szeidl (1970) HSH3 refers to Sawyer Hogg's 3rd (1973) catalogue K96 refers to Kaluzny et al. (1996) K97a refers to Kaluzny et al. (1997a) K97b refers to Kaluzny et al. (1997b) vL refers to van Leeuwen et al. (2000) Wel refers to Weldrake et al. (2007) The data for V411 are from Navarrete et al. (2013). All the data for V412-V450 are from Weldrake et al. (2007). Mean magnitudes have not been listed for these stars because the V magnitudes that they published were not mean values. Also the amplitudes have not been listed because the observations were not made on the standard V system; they are a combination of V and R. The data for V451-V454 and V460 are from Randall et al. (2011,2016). The sdOV classification is based on the system devised by Kilkenny et al. (2013). The data for V455 and V456 are from Navarrete et al. (2015). The data for V457-459 are from Figuera Jaimes et al. (2016) The field status for V240 (Ogle #48), V247 (Ogle #57) and V257 (Ogle #67) was established by Rucinski (2000) who determined that the other EW variables discovered by Kaluzny et al. (1996, 1997a), i.e., the EW stars with numbers in the range V197-V260, are cluster members. Some stars (V368, V372, V384) are labelled f_CM because they are considered to be field stars based on their location on the CM diagram published by Kaluzny et al. (2004). Samus et al. (2009) have pointed out that V1, V2, V56, V65, V78, V129, V133, V168, V269, V283 are listed in the GCVS as NSV 06235 and V0825, V0833, V0813, V0814, V0826, V0594, V0832, V0791, V1045 Cen, respectively. ====================================================================== Notes on individual stars: V19, V21 (Ogle #192, 97): The possible field status for these two stars was suggested by Clement & Rowe (2001) based on their anomalous Fourier parameters when compared with other variables with similar periods. V42: Dickens et al. (1972) listed this star as a "radial velocity" member, but according to van Leeuwen, the proper motion does not indicate cluster membership. Navarrete (2014, private communication) pointed out that V42 is the same star as V395 announced by Kaluzny et al. (2004). V52: van Leeuwen et al. (2000) commented that this star might have an unresolved companion which would account for the fact that it is brighter and has a lower amplitude than other RR Lyrae variables with the same period. V53, V162, V167: These three stars lie on the red giant branch of the CM diagram. Martin (1938) classified V53 and V162 as irregulars and found that V167 exhibited small variations of unknown character. However, Dickens et al. (1972) found that none of these stars exhibited significant variations in their observations. The proper motion study of van Leeuwen et al. (2000) indicated that V167 was not a cluster member. Bellini et al. (2009) derived a 23% membership probability. Kaluzny et al. (2004) pointed out that V167 lies within an arcsec of the X-ray source XMM-25. V56, V168: The field status for these two variables is based on a radial velocity study by Liller & Tokarz (1981) and for V168, the proper motion study of van Leeuwen et al. (2000) also indicated non-membership. The proper motion study of Bellini et al. (2009) indicated membership probability 98% for V56 and non-membership (0%) for V168. V65, V78: The field status for these two variables is based on a radial velocity study by Geyer & Vogt (1978). This was confirmed by the proper motion studies of van Leeuwen et al. (2000) and Bellini et al. (2009). V80: Bailey commented that V80 was difficult to measure because it was too distant from the comparision stars. It seemed to be variable but the range was small. He suggested a period of 0.45 or 0.31. V80 was outside the field of view in subsequent investigations by other authors. V84, V268: The field status for these stars was determined from the proper motion study of van Leeuwen et al. (2000). V268 is Ogle #122 (Kaluzny et al. 1997b). They also noted that the characteristics of the V84 light curve differ from those of other stars with a similar period. V169, V289, V357: These three variables, all of which are considered to be RR1 variables according to Kaluzny et al. (2004), were classified as eclipsing variables by Weldrake et al. (2007). They are Weldrake #42, #43 and #121 respectively. Snce they all lie in the RR Lyrae instability strip in the CM diagram, Kaluzny's classification is assumed to be correct. This conclusion was endorsed by Ed Guinan (2013, private communication). V182, V183: Shokin & Samus (1996) pointed out that the identification for these two stars was highly uncertain because they lie far from the region occupied by most of the variables and no identification chart was published by the discoverer. V186: This star, numbered V184, by Fourcade et al. (1978) in their discovery paper is the same as RGO 320 discussed by Dickens et al. (1972). This was pointed out by Shokin & Samus (1996) and is evident from a comparison of Fourcade's ID chart with the chart published for star #320 by Woolley (1966 - see Plate IX). It was confirmed as a radial velocity cluster member (Feast 1973) and the data listed in the above table are from Dickens et al. (1972). V216, V224 (Ogle #22, 31): Kaluzny et al. (1996) showed that these two variables have similar properties, but their classification is uncertain. Initially, they postulated that they might be spotted variables. However, they later (Kaluzny et al. 2004) classified them as long period variables. Both stars have periods in the 20-40 day range and lie on the RG branch in the CM diagram, at a luminosity level lower than SR variables. V223 (Ogle #30): Kaluzny et al. (2004) noted that this star lies near the X-ray source XMM-29 and also that the proper motion study of van Leeuwen et al. (2001) indicates its probability of membership is in the 0-2% range. The study by Bellini et al. (2009) also indicates a low (0%) membershgip probability. Its position in the CM diagam is also consistent with non-membership in the cluster. V269: This star is RGO 4789 (Woolley 1966) and Ogle #123 (Kaluzny et al. 1997b). It is considered to be a field star. It was one of 5 TiO variables discussed by Dickens et al. (1972) who noted that they needed to determine its radial velocity to establish its membership before discussing it further. In a later paper that included the TiO variables for which membership was established (Feast 1973), RGO 4789 was not included. The non-member status of V269 was confirmed in the proper motion study by van Leeuwen et al. (2000). V282 = Ogle #171 = Weldrake #84: This star was not in the field of view of Kaluzny et al. (2004). In their earlier study (Kaluzny et al. 1997b), they derived a period of 0.5005 days but were unable to assign a classification. Weldrake et al. (2007) derived a period of 0.664 days and showed that the star could be an eclipsing binary. The proper motion study of van Leeuwen et al. indicated that V282 was not a cluster member. V284 = Ogle #173 = Weldrake #129: This star was not in the field of view of Kaluzny et al. (2004), but in their earlier study (Kaluzny et al 1997b), they derived a period of approximately 3.3 days and classified it as a spotted variable. Weldrake et al. (1997b) confirmed this period and also derived a colour index that is more red than expected for a cluster member at the V=18.5 level. It is therefore considered to be a field star. V367, V369, V375, V376, V377, V378, V383: Kaluzny et al. (2004) noted that all of these objects are associated with X-ray sources. The proper motion study of van Leeuwen et al. (2000) indicated that V367, V375, V378 were not cluster members but the other 4 stars were too faint to be included in their investigation. However, based on location in the CM diagram, Kaluzny et al. (2004) concluded that none of these stars are cluster members. The proper motion study by Bellini et al. (2009) supported this conclusion except in the case of V369 and V383 for whch they found membership probabilties greater than 90%. A subsequent spectroscopic study by Rozyczka et al. (2012) showed that V369 is not a cluster member. V378 = Weldrake #166: Kaluzny et al. (2004) noted that this star is an eclipsing binary with its light curve affected by chromospheric activity. V365, V368, V370, V381, V388, V403, V410: The field status for these variables is based on the proper motion study of Bellini et al. (2009). V395: Navarrete (2014, private communication) pointed out that V395 is V42. V406, V409 = Weldrake 39, 161: These stars were classified as possible Algol-like eclipsing binaries (EA) by Kaluzny et al. (2004), but they did not derive periods. The periods listed in the above table were determined by Weldrake et al. (2007). ====================================================================== Discovery of the variable stars in Omega Centauri: V1-132 Bailey (1902) with an ID chart (Plate I, Frontispiece) and x,y coordinates (Table VI, pages 133-135). By the time he published his paper, he considered V28, 31, 37 and 93 to be non-variable (see page 14) and this conclusion was later confirmed by Martin (1938) and by Kaluzny et al. (2004). V133-165 discovered by van Gent and Hertzsprung and announced by Martin (1938) with x,y coordinates (bottom of page 20, Table 5 on pages 22-27 or Table 6 on page 35) and ID charts (Plates I and II). V133 and V159 were outside the field of his ID charts and were later identified on ID charts by van Gent (1948). All of Bailey's variables (except V80) are labelled on Martin's charts. V166-167 Martin (1938) with ID charts (Plates I and II) and x,y coordinates (bottom of page 20). Martin assigned these numbers to his comparison stars 89b and p3, (see page 16 and 18 of his paper) V168 Kooreman (1942) with x,y coordinates V169 Belserene (1956) with x,y coordinates V170 = star G of Belserene (1959) who published x,y coordinates Eggen (1961a,b) detected its variability. The number V170 was assigned by Sawyer Hogg (1973) who also identified it as RGO #53 (Woolley 1966). Woolley established that it is a cluster member. However, it was not included in the studies of red variables in Omega Cen by Dickens et al. (1972). V171-180 = V1-10 of Wilkens (1965) who published ID charts and x,y, coordinates. The numbers V171-180 were assigned by Sawyer Hogg (1973). Wilkens (1965) listed 5 additional variables, V11-15, but according to Sawyer Hogg (1973), he later indicated (Letter, 1972) that these were suspected variables. V181-183 Wesselink (1969,1972 in private correspondence with Sawyer Hogg) The numbers V181-183 were assigned by Sawyer Hogg (1973) who also published Wsselink's x,y coordinates and periods. V184-185 Butler et al. (1978) with no ID By matching periods and approximate distance from the cluster centre, Clement & Rowe (2000) determined that V184=Ogle #191 and V185=Ogle #71 from the investigation of Kaluzny et al. (1997b). Kaluzny et al. published RA, dec and X,Y pixel positions. V186 =V184 of Fourcade et al. (1978) with ID chart and x,y coordinates The number V186 was assigned in our electronic catalogue (Clement et al. 2001) because Butler et al. (1978) had assigned the number 184 to a different star. Fourcade's variable is the same star as RG 320 that was discussed by Dickens et al. (1972) and confirmed as a cluster member by Feast (1973 - page 138). V187-193 = eclipsing binary candidates NJL #221, 216, 58, 1, 218, 5, 212 of Niss et al. (1978) who published x,y coordinates and an ID chart. The numbers 187-193 were assigned in our electronic catalogue (Clement et al. 2001). Niss et al. stated that NJL#5 was almost certainly eclipsing and that the other six were reasonably certain variables. A subsequent study by Kaluzny et al. (1996) confirmed the variability of NJL #5 (=Ogle #18), but did not list the other six as variables. In a later paper, Kaluzny et al. (2004) announced that none of the other six were variable. Margon & Cannon (1989) measured the radial velocity of NJL#5 and established its cluster membership. V194 = candidate variable NJL #220 of Niss et al. (1978) who published x,y coordinates and an ID chart. Its variability was later confirmed by Niss (1981). The number 194 was assigned in our electronic catalogue (Clement et al. 2001). V195 = star NJL #79 of Niss et al. (1978) who published x,y coordinates and an ID chart. Jorgensen (1982) detected its variability and the number V195 was assigned in our electronic catalogue (Clement et al. 2001). V196 = E39 of Jorgensen & Hansen (1984) with ID chart The number V196 was assigned in our electronic catalogue (Clement et al. 2001). V197-233 = Ogle #1-4, 6-17, 19-22, 24-40 of Kaluzny et al. (1996) with RA and dec and X,Y pixel positions The numbers V197-233 were assigned in our electronic catalogue (Clement 2001). V234-260 = Ogle #41, 43-49, 51, 53-70 of Kaluzny et al. (1997a) with RA and dec and X,Y pixel positions The numbers V234-260 were assigned in our electronic catalogue (Clement 2001). V261-291 = Ogle #81, 95-96, 108, 111, 115, 121-123, 131-132, 134, 139, 148-149, 152, 155-156, 161-162, 167, 171-173, 177, 186, 196, 202-203, 208-209 of Kaluzny et al. (1997b) with RA and dec and X,Y pixel positions The numbers V261-291 were assigned in our electronic catalogue (Clement 2001). V292-293 = #50259 and #55071 van Leeuwen et al. (2000) with RA and dec The numbers V292-293 were assigned in the 2002 update to the Clement (2001) on-line catalog and were adopted by Kaluzny et al. (2004) when they published their catalog. van Leeuwen et al. listed two other candidate red variables that were cluster members: #37110 (RA 13:26:34.12, dec -47:26:21.1) #39105 (RA 13:26:25.00, dec -47:27:06.3) which is star #201 in Woolley's (1966) study. V294-410 = NV294-410 with RA, dec and individual finder charts Kaluzny et al. (2004) V411 = V133 of Weldrake et al. (2007) who published RA and dec They stated that this star was the same as V144 of Kaluzny et al. (2004), but Navarrete et al. (2013) showed that Weldrake's #133 was a different star, not previously known to be variable. They assigned the number V411 and published an ID chart for both V144 and V411. V412-450 Weldrake et al. (2007) with RA and dec They introduced their own numbering system which was different from the one that is generally used for Omega Cen, i.e. the system started by Bailey (1902) and continued by Martin (1938) and subsequent investigators. The Weldrake (W) numbers are indicated in the ID column of the above table. Weldrake et al. announced 81 new variables, but only 43 are included here. Variables for which they derived an amplitude less than 0.05 mag (W1, W4, W15, W58, W68, W69, W86, W93, W98, W125, W126, W130, W132, W187) have been excluded. In addition, variables which appear to be field stars based on their location in the CM diagram (e.g. W5, W6, etc.) and variables with 0% probability of membership (W31, W59), based on the proper motion study of Bellini et al. (2009) are also excluded. Future investigations might show that some of these stars are variables that belong to Omega Centauri. V451-454 = Randall's V1-4 with RA and dec Randall et al. (2011) published the coordinates and summarized the properties of these rapidly pulsating extreme horizontal branch (EHB) stars. Three of them had been announced in earlier papers by Randall and collaborators. Finding charts were later published by Randall et al. (2016). A fifth candidate was announced by Randall et al. (2013), but no position was published. V455-456 = NV455 and NV 456 of Naverrete et al. (2015) who published finder charts and RA and dec (epoch 2000). They also announced two other new RR Lyrae variables, NV457 and NV458, but their locations on the CM diagram indicate that they are too faint to be cluster members. V457-459 Figuera Jaimes et al. (2016) with RA, dec and a finder chart V460 = Randall's V5 (another EHB star) with finding chart and RA and dec Randall et al. (2016) Randall et al. (2016) also detected an EHB variable with an apparent periodicity of approximately 0.03 days and speculated on possible explanations for its observed luminosity variation. PSR: According to Paulo Freire's website at the Max Planck Institute in Bonn (July 2024 version), there are 18 millisecond pulsars in Omega Centauri (NGC 5139) --------------------------------------------------------------------- A study of the variable stars in Omega Centauri is currently being undertaken with the New Technology Telescope (La Silla, ESO). On six consecutive nights in April 2011, observations were obtained with a sampling time of 15 seconds in three wavelength bands: Sloan u', g' and r'. The data will be used to analyse light curves of RR Lyrae, SX Phoenicis, eclipsing binaries and semi-regular variables. Preliminary results for a sample of RR Lyrae variables were presented by Calamida et al. (2013). -------------------------------------------------------------------- In a search for tidal tails around Omega Centarui, Fernandez-Trincado et al. (2015) have discussed the properties of 48 RR Lyrae variables in an area 50 square degrees around the cluster. Of these, 37 are new discoveries, but all of them are outside the tidal radius of the cluster. --------------------------------------------------------------------- Cool et al. (2013) reported optical counterparts for approximately 40 Chandra X-ray sources that are probably associated with the cluster. These include 27 candidates, 3 BY Drcaonis stars, 1 qLMXB and 7 possible magnetically active binaries. ===================================================================== References Bailey, S.
