Pulsating stars in eclipsing binary stars and exoplanets

ABSTRAKT / ABSTRACT :

Many eclipsing binary stars, exoplanets, or exoplanet candidates show pulsations of one or both components.
The additional light-curve variability caused by the pulsations complicates the binary star or exoplanet
analysis. On the other hand, a reliable determination of the absolute parameters of the pulsating component
(mass, radius, and luminosity) is important for a better understanding of stellar pulsations and calibration
of so-called scaling relations, especially in p-mode pulsators. In some close binary systems and possibly
systems with massive exoplanets, the pulsations can be tidally induced with an integer ratio of pulsational
and orbital period. The TESS and Kepler photometric missions are an excellent source of pulsators in
eclipsing binary stars. An analysis of several exoplanet candidates and binary stars with a pulsating
component(s) is presented. The case of an interesting processing exoplanet candidate with a pulsating
component is presented.
