NIGHT: a compact, near-infrared, high-resolution spectrograph to survey helium in exoplanet systems
C. Farret Jentink, V. Bourrier, C. Lovis +5
Among highly irradiated exoplanets, some have been found to undergo significant hydrodynamic expansion traced by atmospheric escape. To better understand these processes in the con…
TOI-858 B b: A hot Jupiter on a polar orbit in a loose binary
J. Hagelberg, L. D. Nielsen, O. Attia +30
We report the discovery of a hot Jupiter on a 3.28-day orbit around a 1.08 M G0 star that is the secondary component in a loose binary system. Based on follow-up radial vel…
The space weather around the exoplanet GJ 436 b. II. Stellar wind-exoplanet interactions
A. A. Vidotto, V. Bourrier, R. Fares +5
The M dwarf star GJ 436 hosts a warm-Neptune that is losing substantial amount of atmosphere, which is then shaped by the interactions with the wind of the host star. The stellar w…
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…
CHEOPS's hunt for exocomets: photometric observations of 5 Vul
Isabel Rebollido, Sebastian Zieba, Daniela Iglesias +3
The presence of minor bodies in exoplanetary systems is in most cases inferred through infra-red excesses, with the exception of exocomets. Even if over 35 years have passed since…
