Characterization of the HD 108236 system with CHEOPS and TESS. Confirmation of a fifth transiting planet
S. Hoyer, A. Bonfanti, A. Leleu +87
The HD108236 system was first announced with the detection of four small planets based on TESS data. Shortly after, the transit of an additional planet with a period of 29.54d was…
A transit survey to search for planets around hot subdwarfs: I. methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS
V. Van Grootel, F. J. Pozuelos, A. Thuillier +79
Context. Hot subdwarfs experienced strong mass loss on the Red Giant Branch (RGB) and are now hot and small He-burning objects. Aims. In this project we aim to perform a transit su…
Dark skies of the slightly eccentric WASP-18 b from its optical-to-infrared dayside emission
A. Deline, P. E. Cubillos, L. Carone +86
We performed a joint analysis of phase-curve observations of the ultra-hot Jupiter WASP-18 b from the visible to the mid-infrared, using data from CHEOPS, TESS and Spitzer. We aim…
A close outer companion to the ultra-hot Jupiter TOI-2109 b?
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +86
Hot Jupiters with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, leadi…
Characterising TOI-732 b and c: New insights into the M-dwarf radius and density valley
A. Bonfanti, M. Brady, T. G. Wilson +88
TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. By doubling the number of available space-based observations a…
A stellar occultation by the transneptunian object (50000) Quaoar observed by CHEOPS
B. E. Morgado, G. Bruno, A. R. Gomes-Júnior +82
Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on the photometric accuracy, the t…
