TOI-3884 b: A rare 6-R planet that transits a low-mass star with a giant and likely polar spot

J. M. Almenara, X. Bonfils, T. Forveille +19

The Transiting Exoplanet Survey Satellite mission identified a deep and asymmetric transit-like signal with a periodicity of 4.5 days orbiting the M4 dwarf star TOI-3884. The signa…

A More Precise Mass for GJ 1214 b and the Frequency of Multi-Planet Systems Around Mid-M Dwarfs

Ryan Cloutier, David Charbonneau, Drake Deming +2

We present an intensive effort to refine the mass and orbit of the enveloped terrestrial planet GJ 1214 b using 165 radial velocity (RV) measurements taken with the HARPS spectrogr…

TOI-674b: an oasis in the desert of exo-Neptunes transiting a nearby M dwarf

F. Murgas, N. Astudillo-Defru, X. Bonfils +59

We use TESS, Spitzer, ground-based light curves and HARPS spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate TOI-6…

The SOPHIE search for northern extrasolar planets -- XVII. A wealth of new objects: Six cool Jupiters, three brown dwarfs, and 16 low-mass binary stars

S. Dalal, F. Kiefer, G. Hébrard +30

Distinguishing classes within substellar objects and understanding their formation and evolution need larger samples of substellar companions such as exoplanets, brown dwarfs, and…

TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA

M. Cointepas, J. M. Almenara, X. Bonfils +59

We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…

Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley

Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69

We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…
