Kepler and TESS: Observing Stellar and Planetary Variability on Decadal Timescales
|Date||2 June 2021|
The NASA Kepler and Transiting Exoplanet Survey Satellite (TESS) missions have revolutionized the field of exoplanets through their high-cadence, high-precision monitoring of regions of the sky. While they were designed with the primary science goal of detecting few-hour planet transit events, they are tremendous laboratories to understand the variability of stars and their circumstellar environments over 10 years or more. Here, I will discuss how these two missions have provided the opportunity to identify and characterise some of this variability, how new data analysis techniques have enabled us to make the most of these data for science beyond exoplanet discovery, and how we can use these missions to probe the evolution of both planetary and stellar systems.
