Radial velocity homogeneous analysis of M dwarfs observed with HARPS. II. Detection limits and planetary occurrence statistics
L. Mignon, X. Delfosse, N. Meunier +13
We re-determine planetary occurrences around M dwarfs using 20 years of observations from HARPS on 197 targets. The first aim of this study is to propose more precise occurrence ra…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS I. Exoplanet detection and candidates
L. Mignon X. Delfosse, X. Bonfils, N. Meunier +11
The census of planets around M dwarfs in the solar neighbourhood meets two challenges: detecting the best targets for the future characterisation of planets with ELTs, and studying…
GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star
Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru +75
Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution p…
HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
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…
