Validating Gaia DR3 Pulsating Variable Classifications with TESS: Building Reliable $\delta$ Scuti and $\gamma$ 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 TESS data. Aiming for reliable catalogs of bona fide $\delta$ Scuti and $\gamma$ Doradus stars, I have validated 1715 $\delta$ Scuti stars, 1403 $\gamma$ 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 $\gamma$ Doradus components.
