Characterisation of the TOI-421 planetary system using CHEOPS, TESS, and archival radial velocity data

A. F. Krenn, D. Kubyshkina, L. Fossati +88

The TOI-421 planetary system contains two sub-Neptune-type planets and is a prime target to study the formation and evolution of planets and their atmospheres. The inner planet is…

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…

TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906

Amy Tuson, Didier Queloz, Hugh P. Osborn +119

We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…

Refined parameters of the HD 22946 planetary system and the true orbital period of planet d

Z. Garai, H. P. Osborn, D. Gandolfi +85

Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…

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
