Using the Gaia Excess Uncertainty as a Proxy for Stellar Variability and Age
Stars are known to be more active when they are young, resulting in a strong correlation between age and photometric variability. The amplitude variation between stars of a given age is large, but the age–variability relation becomes strong over large groups of stars. We explore this relation using...
