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…
