Variability Census of Legacy Catalogs. II. 6600+ New δ Scuti and γ Doradus Stars*

Abstract

Abstract From Phase II of a variability vetting census in BD, HD, SAO and PPM catalogs, I have identified a total of new variables of over 5000 δ Scuti, 3500 γ Doradus, 1200 Maia variables, 4 RR Lyrae stars, 420 eclipsing binaries, 5500 rotating variables (220+ ellipsoidal variable stars, 550+ ACV and several other subtypes including solar-like oscillators), and other types. Notably, more than 66 eclipsing binary systems have been identified with pulsating primary components of either DSCT or GDOR type, while 10 more binaries feature overlapping Maia-type pulsation. Moreover, over 960 of these variables exhibit hybrid δ Sct-γ Dor pulsations.
