Abstract:The light curves of tidally locked hot Jupiters transiting fast-rotating, early-type stars are a rich source of information about both the planet and star, with full-phase coverage enabling a detailed atmospheric characterisation of the planet. Although it is possible to determine the true spin-orbit angle Psi -- a notoriously difficult parameter to measure -- from any transit asymmetry resulting from gravity darkening induced by the stellar rotation, the correlations that exist between the transit parameters have led to large disagreements in published values of Psi for some systems. We aimed to study these phenomena in the light curves of the ultra-hot Jupiter MASCARA-1 b, which is characteristically similar to well-studied ...(more)
Abstract: (hide)
We present photometric light curves observed by CHEOPS, containing three occultations and two transits of MASCARA-1 b. Occultation 1 is not included in the joint analysis, and is analysed separately in section 3.1.
