The Rossiter-McLaughlin effect and exoplanet transits: A delicate association at medium and low spectral resolution

Yann Carteret, Vincent Bourrier, William Dethier

The characterization of exoplanetary atmospheres via transit spectroscopy is based on the comparison between the stellar spectrum filtered through the atmosphere and the unadultera…

The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…

The SOPHIE search for northern extrasolar planets-XIX. A system including a cold sub-Neptune potentially transiting a V = 6.5 star HD88986

N. Heidari, I. Boisse, N. C. Hara +51

Transiting planets with orbital periods longer than 40 d are extremely rare among the 5000+ planets discovered so far. The lack of discoveries of this population poses a challenge…

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…
