Validating Gaia DR3 Pulsating Variable Classifications with TESS: Building Reliable δ Scuti and γ Doradus Stars Catalogs (In Progress)
Abstract
Gaia DR3 revealed 748,058 pulsating variable stars of mixed DSCT∣GDOR∣SXPHE types. This project undertakes a comprehensive examination to validate and distinguish these stars using Transiting Exoplanet Survey Satellite data. Aiming for reliable catalogs of bona fide δ Scuti and γ Doradus stars, I have validated 1715 δ Scuti stars, 1403 γ Doradus stars, and identified 260 eclipsing binaries, one RR Lyrae star, and 460+ rotating variables from an initial sample of 16,690 objects. Notably, 15 of the newfound eclipsing binaries harbor pulsating γ Doradus components. *Dedicated to my wife Jingyun Zhang.
