TOI-5678 b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS
S. Ulmer-Moll, H. P. Osborn, A. Tuson +92
A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have a precise radius measurement…
Hint of an exocomet transit in the CHEOPS lightcurve of HD 172555
F. Kiefer, V. Van Grootel, A. Lecavelier des Etangs +72
HD172555 is a young (20Myr) A7V star surrounded by a 10au wide debris disk suspected to be replenished partly by collisions between large planetesimals. Small eva…
The stable climate of KELT-9b
K. D. Jones, B. M. Morris, B. -O. Demory +76
Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as the hottest planet thus far discovered with a dayside temperature of over 4500K. At t…
Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076
Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93
Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…
The atmosphere and architecture of WASP-189 b probed by its CHEOPS phase curve
A. Deline, M. J. Hooton, M. Lendl +83
Gas giants orbiting close to hot and massive early-type stars can reach dayside temperatures that are comparable to those of the coldest stars. These "ultra-hot Jupiters" have atmo…
CHEOPS observations of the HD 108236 planetary system: A fifth planet, improved ephemerides, and planetary radii
A. Bonfanti, L. Delrez, M. J. Hooton +106
The detection of a super-Earth and three mini-Neptunes transiting the bright ( = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and…
The hot dayside and asymmetric transit of WASP-189b seen by CHEOPS
M. Lendl, Sz. Csizmadia, A. Deline +102
The CHEOPS space mission dedicated to exoplanet follow-up was launched in December 2019, equipped with the capacity to perform photometric measurements at the 20 ppm level. As CHEO…
