"The evolution of cool stars and the planets they host"
Though tremendous progress has been made to understand the population of exoplanets as a whole, we still know little about how planets evolve over time for one main reason: the ages of stars are difficult to measure. There are many methods for measuring stellar ages but rotation-dating, also known as 'gyrochronology', may be unparalleled for cool main-sequence stars. In this talk I will discuss the potential of gyrochronology and recent advances made in understanding the rotational and magnetic evolution of cool stars. I will outline progress in, and prospects for, measuring both the ages and rotation periods of stars across the Galaxy using current and future surveys, including TESS, ZTF, and LSST. Finally, I'll discuss the application of measuring stellar ages to inferring the evolutionary pathways of planetary systems.
