Architecture of TOI-561 planetary system
G. Piotto, T. Zingales, L. Borsato +89
We present new observations from CHEOPS and TESS to clarify the architecture of the planetary system hosted by the old Galactic thick disk star TOI-561. Our global analysis, which…
CHEOPS in-flight performance: A comprehensive look at the first 3.5 years of operations
A. Fortier, A. E. Simon, C. Broeg +128
CHEOPS is a space telescope specifically designed to monitor transiting exoplanets orbiting bright stars. In September 2023, CHEOPS completed its nominal mission and remains in exc…
Detailed cool star flare morphology with CHEOPS and TESS
G. Bruno, I. Pagano, G. Scandariato +79
Context. White-light stellar flares are proxies for some of the most energetic types of flares, but their triggering mechanism is still poorly understood. As they are associated wi…
No random transits in CHEOPS observations of HD 139139
R. Alonso, S. Hoyer, M. Deleuil +78
HD 139139 (a.k.a. 'The Random Transiter') is a star that exhibited enigmatic transit-like features with no apparent periodicity in K2 data. The shallow depth of the events (2…
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…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS
A. Bonfanti, D. Gandolfi, J. A. Egger +89
TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…
A full transit of Lupi d and the search for an exomoon in its Hill sphere with CHEOPS
D. Ehrenreich, L. Delrez, B. Akinsanmi +90
The planetary system around the naked-eye star Lupi (HD 136352; TOI-2011) is composed of three exoplanets with masses of 4.7, 11.2, and 8.6 Earth masses. The TESS and CHEOPS…
