Asteroseismology uses the natural oscillation modes of stars to
study their interiors. The wonderfully precise measurements by NASA’s
Kepler and TESS missions are ideal data sources for the technique. These
space telescopes have been monitoring the brightness of hundreds of
thousands of stars, with the main goal of discovering extra-solar planets
as they transit their parent stars. At the same time, observations of
stellar oscillations have led to a revolution in asteroseismology. I will
discuss some of the key results, including the use of gravity modes to
probe the cores of red giant stars, the characterization of stars found to
host exoplanets, and the measurement of ages for young stellar
associations.
