Validating Gaia DR3 Pulsating Variable Classifications with TESS: Building Reliable δ Scuti and γ Doradus Stars Catalogs (In Progress)*

Research Notes of the AAS
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 ...

The Delta Scuti variable AI Canum Venaticorum - Short-period variables, spectroscopic binaries, and the Bright Star Catalogue

Publications of the Astronomical Society of the Pacific, 1990
The observational history of the Delta Scuti star AI CVn wasa traced, and it was found to be incomplete and contradictory. It is suggested that the star is misclassified as a spectroscopic binary in The Bright Star Catalogue and that simultaneous spectroscopic and photometric observations are needed to determine the true nature of this star.

The study of short orbital period of delta scuti pulsating variable stars

Proceedings of the International Astronomical Union, 2019
AbstractAs a pulsating star moves in its binary orbit, the path length of the light between us and the star varies, leading to the periodic variation in the arrival time of the signal from the star to us (earth). With the consideration of pulsators light arrival time delay effects several new methods which allows using Kepler photometric data (light ...

Rapidly oscillating Ap stars and Delta Scuti variables

2008
The discovery of the rapidly oscillating Ap stars has raised many questions concerning the relationship among 6 Sct variables, Ap stars, and other apparent non-varying stars in the 6 Set instability strip. In this paper, the present status of our under standing of the rapidly oscillating Ap stars and the δ Set stars is reviewed, but the former class is
