Title: Modeling exoplanet transits of rapid rotators.

Author: T. Pribulla, AI SAS

Abstract:

Modeling exoplanets transiting rapidly rotating stars is important not
only for the exoplanet research but also for improving our knowledge on
the early-type stars. Including gravity darkening, Doppler beaming and
ellipsoidal deformation due to rotation is a must when modeling
high-precision satellite photometry. Transition from the spherical stars
or ellipsoids to Roche geometry is computationally costly but necessary in
the case of close-in giant planets. The application of a new code to
Kepler-13 transits and first results of modelling three rapidly rotating
planet hosts observed with the CHEOPS satellite are presented.
