Chromaticity of stellar activity in radial velocities : Anti-correlated families of lines on the M dwarf EV Lac with SPIRou and SOPHIE

Pierre Larue, Xavier Delfosse, Andres Carmona +33

Context. In the search for exoplanets using radial velocities (RV), stellar activity has become one of the main limiting factors for detectability. Fortunately, activity-induced RV…

Characterizing planetary systems with SPIRou: Detection of a sub-Neptune in a 6-day period orbit around the M dwarf Gl 410

A. Carmona, X. Delfosse, M. Ould-Elhkim +42

The search for exoplanets around nearby M dwarfs represents a crucial milestone in the census of planetary systems in the vicinity of our Solar System. Since 2018 our team is carry…

Gl 725A b: a potential super-Earth detected with SOPHIE and SPIRou in an M dwarf binary system at 3.5 pc

P. Cortes-Zuleta, I. Boisse, M. Ould-Elhkim +34

We report the discovery of a super-Earth candidate orbiting the nearby mid M dwarf Gl\,725A using the radial velocity (RV) method. The planetary signal has been independently ident…

TOI-3568 b: a super-Neptune in the sub-Jovian desert

E. Martioli, R. P. Petrucci, E. Jofre +42

The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…

TOI-2374 b and TOI-3071 b: two metal-rich sub-Saturns well within the Neptunian desert

Alejandro Hacker, Rodrigo F. Díaz, David J. Armstrong +40

We report the discovery of two transiting planets detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V and an F8V star, respectiv…

Evidence for transit-timing variations of the 11 Myr exoplanet TOI-1227 b

J. M. Almenara, X. Bonfils, T. Guillot +27

TOI-1227 b is an 11 Myr old validated transiting planet in the middle of its contraction phase, with a current radius of 0.85 R. It orbits a low-mass pre-main sequence star (0.…
