Searching for hot water world candidates with CHEOPS: II. A low-density super-Earth orbiting the K dwarf TOI-2211
J. A. Egger, P. Cortés-Zuleta, D. Kubyshkina +98
Small exoplanets on close-in orbits are exposed to high levels of stellar irradiation, which can effectively remove low-mass primordial H/He envelopes through atmospheric escape. U…
In-situ observations of resident space objects with the CHEOPS space telescope
Nicolas Billot, Stephan Hellmich, Willy Benz +80
The CHaracterising ExOPlanet Satellite (CHEOPS) is a partnership between the European Space Agency and Switzerland with important contributions by 10 additional ESA member States.…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
Refining the properties of the TOI-178 system with CHEOPS and TESS
L. Delrez, A. Leleu, A. Brandeker +84
The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with orbital periods between 1.9 and 20.7 days. All planets…
CHEOPS and TESS view of the ultra-short period super-Earth TOI-561 b
J. A. Patel, J. A. Egger, T. G. Wilson +75
Ultra-short period planets (USPs) are a unique class of super-Earths with an orbital period of less than a day and hence subject to intense radiation from their host star. While mo…
Investigating the visible phase-curve variability of 55 Cnc e
E. A. Meier Valdés, B. M. Morris, B. -O. Demory +87
55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux modulation that is phased with th…
