Glueing CSC to Gaia to probe stellar activity evolution
Abstract
X-ray stellar surveys show there are problems in our understanding of the evolution of stellar magnetic activity and star formation history in our neighbourhood. Matching sources from the Chandra Source Catalog (CSC) with Gaia will provide a major improvement in our understanding by allowing comparisons with predictions from state-of-the-art models of stellar activity. We will build the first detailed picture of the evolution of magnetic dynamos and coronal heating for stars with ages 1-10 Gyr, probe the disk star formation history, and test conclusions of population surveys that find an excess of young yellow stars. We will use ML methods to remove ambiguity in multiple matches. Our work will add value to the CSC by building one of the cleanest stellar matched samples possible.
