Pulsating stars with substellar companions

There is a small number of known pulsating stars with transiting exoplanets. The analysis of such systems is challenging because the pulsation distorts the transits and therefore, the proper subtraction of the pulsation pattern is essential in order to model the transit light curves correctly. In addition, in close systems, the tidal forces of the companion may influence the oscillations. We performed photometric analysis of such systems using TESS space telescope data. We modeled the transit light curves and determined the basic parameters of the systems. We also found evidence of tidally perturbed stellar oscillations related to the substellar companions.
