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 ...

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.

DISCOVERY AND CATALOGING OF A NEW DELTA SCUTI STAR IN PERSEUS

Open European Journal on Variable Stars
In this work, we present the discovery and cataloguing of a new variable star in Perseus. After its photometric study, it was concluded that we were facing a new  Scuti type variable star which, although it was included in the ZTF catalogue of periodic ...
