  • Title of programme: Rapidly rotating stars and their transiting planets: a unique laboratory of many astrophysical effects
  • Abstract: We propose a mini-survey of rapidly rotating early-type main-sequence stars with transiting planets, similar to the Kepler-13 system, to constrain their planetary and stellar parameters, and to characterize the star-planet interactions in these cases. For this mini-survey we have selected the KELT-17, KELT-19A and KELT-21 planetary systems. Some astrophysical effects in such systems are not well understood yet, since there are no sufficiently precise photometric observations. Based on the precise CHEOPS transit light curves of the systems, we aim to search for similar asymmetries, as it was detected in the Kepler-13 system, and to study some astrophysical effects simultaneously.

Mission Description CHEOPS (Benz et al., https://doi.org/10.1007/s10686-020-09679-4) is a European Space Agency (ESA) mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the United Kingdom.

The satellite has a single payload comprising an ultra-high precision photometer covering the 330 - 1100 nm wavelength range in a single photometric band. Observations are made as part of the Guaranteed Time Observing Programme that is formulated by the CHEOPS Science Team, and the Guest Observers Programme through which the Community at large can apply for CHEOPS time.
