An explosion of space-based photometric data in the last decade from the Kepler and TESS missions has given us an unprecedented amount of information on stars across the HR diagram. On the main sequence this has led to an expansion of our understanding of how the rotation rates of Sun-like stars evolves as they age. This relationship between age and rotation, called gyrochronology can be used to age-date stars for various purposes, from measuring the ages of exoplanet hosts to determining groups of stars born together. In this talk I’ll go through two different ways we can measure stellar rotation – through asteroseismology and star spot variability – and how both contribute to a more comprehensive understanding of stars and stellar evolution.
