Bright Opportunities for Atmospheric Characterization of Small Planets: Masses and Radii of K2-3 b, c, d and GJ3470 b from Radial Velocity Measurements and Spitzer Transits
Molly R. Kosiarek, Ian J. M. Crossfield, Kevin K. Hardegree-Ullman +36
We report improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit obser…
Confirmation of the radial velocity super-Earth K2-18c with HARPS and CARMENES
R. Cloutier, N. Astudillo-Defru, R. Doyon +13
In an earlier campaign to characterize the mass of the transiting temperate super-Earth K2-18b with HARPS, a second, non-transiting planet was posited to exist in the system at $\s…
Extrasolar planets and brown dwarfs around AF-type stars. X.The SOPHIE northern sample. Combining the SOPHIE and HARPS surveys to compute the close giant planet mass-period distribution around AF-type stars
S. Borgniet, A. -M. Lagrange, N. Meunier +31
The impact of the stellar mass on the giant planet properties is still to be fully understood. Main-Sequence (MS) stars more massive than the Sun remain relatively unexplored in ra…
The CARMENES search for exoplanets around M dwarfs. A Neptune-mass planet traversing the habitable zone around HD 180617
A. Kaminski, T. Trifonov, J. A. Caballero +37
Despite their activity, low-mass stars are of particular importance for the search of exoplanets by the means of Doppler spectroscopy, as planets with lower masses become detectabl…
A second terrestrial planet orbiting the nearby M dwarf LHS 1140
Kristo Ment, Jason A. Dittmann, Nicola Astudillo-Defru +27
LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and Spitzer as well as…
The 55 Cnc system reassessed
V. Bourrier, X. Dumusque, C. Dorn +9
Orbiting a bright, nearby star the 55 Cnc system offers a rare opportunity to study a multiplanet system that has a wide range of planetary masses and orbital distances. Using two…
The SOPHIE search for northern extrasolar planets XIII. Two planets around M-dwarfs Gl617A and Gl96
M. J. Hobson, R. F. Díaz, X. Delfosse +32
We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE…
Radial velocity follow-up of GJ1132 with HARPS. A precise mass for planet 'b' and the discovery of a second planet
X. Bonfils, J. -M. Almenara, R. Cloutier +19
GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm t…
Optical and Near-Infrared Radial Velocity Content of M Dwarfs: Testing Models with Barnard's Star
Étienne Artigau, Lison Malo, René Doyon +3
High precision radial velocity (RV) measurements have been central in the study of exoplanets during the last two decades, from the early discovery of hot Jupiters, to the recent m…
Eyes on K2-3: A system of three likely sub-Neptunes characterized with HARPS-N and HARPS
M. Damasso, A. S. Bonomo, N. Astudillo-Defru +67
M-dwarf stars are promising targets for identifying and characterizing potentially habitable planets. K2-3 is a nearby (45 pc), early-type M dwarf hosting three small transiting pl…
