Context. Planetary companions of a fixed mass induce reflex motions with a larger amplitude around lower-mass stars, which adds to making M dwarfs excellent targets for extra-solar planet searches. The most recent velocimeters with a stability of similar to 1 m s(-1) can detect very low-mass planets out to the habitable zone of these stars. Low-mass small planets are abundant around M dwarfs, and most of the known potentially habitable planets orbit one of these cool stars. Aims. Our M-dwarf… Expand
The HARPS search for southern extra-solar planets XLI. A dozen planets around the M dwarfs GJ 3138, GJ 3323, GJ 273, GJ 628, and GJ 3293
Context. Low mass stars are currently the best targets for searches for rocky planets in the habitable zone of their host star. Over the last 13 years, precise radial velocities measured with theExpand
The mass of planet GJ 676A b from ground-based astrometry - A planetary system with two mature gas giants suitable for direct imaging
The star GJ 676A is an M0 dwarf hosting both gas-giant and super-Earth-type planets that were discovered with radial-velocity measurements. Using FORS2/VLT, we obtained position measurements of theExpand
The SOPHIE search for northern extrasolar planets: XIII. Two planets around M-dwarfs Gl617A and Gl96
We present the detection of a warm Neptune orbiting the M dwarf Gl 378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provence. The star wasExpand
A temperate exo-Earth around a quiet M dwarf at 3.4 parsec
The combination of high-contrast imaging and high-dispersion spectroscopy, which has successfully been use to detect the atmosphere of a giant planet, is one of the most promising potential probes ofExpand
Radial velocity follow-up of GJ1132 with HARPS: A precise mass for planet b and the discovery of a second planet
The source 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 theExpand
A rocky planet transiting a nearby low-mass star
M-dwarf stars—hydrogen-burning stars that are smaller than 60 per cent of the size of the Sun—are the most common class of star in our Galaxy and outnumber Sun-like stars by a ratio of 12:1. RecentExpand
A temperate rocky super-Earth transiting a nearby cool star
TLDR
Observations of LHS 1140b, a planet with a radius of 1.4 Earth radii transiting a small, cool star (L HS 1140) 12 parsecs away, measure the mass of the planet to be 6.6 times that of Earth, consistent with a rocky bulk composition, and place an upper limit on the orbital eccentricity. Expand
The SOPHIE search for northern extrasolar planets
We present the detection of a warm Neptune orbiting the M dwarf Gl 378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provence. The star wasExpand
Radial velocity studies of cool stars
TLDR
It is found that the mass of M dwarf planets is relatively much lower than the expected mass dependency based on stellar mass and thus it is inferred that planet formation efficiency around low-mass stars is relatively impaired. Expand
Optical and Near-Infrared Radial Velocity Content of M Dwarfs: Testing Models with Barnard's Star
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 mass measurements ofExpand
