A terrestrial planet candidate in a temperate orbit around Proxima Centauri
Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units.
We have conducted a kinematic study of 165 young M dwarfs with ages of 300?Myr. Our sample is composed of stars and brown dwarfs with spectral types ranging from K7 to L0, detected by ROSAT and with
The habitability of Proxima Centauri b. I. Irradiation, rotation and volatile inventory from formation to the present
Proxima b is a planet with a minimum mass of 1.3 MEarth orbiting within the habitable zone (HZ) of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we investigate a
State of the Field: Extreme Precision Radial Velocities*
The Second Workshop on Extreme Precision Radial Velocities defined circa 2015 the state of the art Doppler precision and identified the critical path challenges for reaching 10 cm s^(−1) measurement

CARMENES instrument overview
This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M
Color difference makes a difference: four planet candidates around tau Ceti
The removal of noise typically correlated in time and wavelength is one of the main challenges for using the radial velocity method to detect Earth analogues. We analyze radial velocity data of tau
CARMENES. I: instrument and survey overview
CARMENES (Calar Alto high-Resolution search for M dwarfs with Exo-earths with Near-infrared and optical Echelle Spectrographs) is a next-generation instrument for the 3.5m telescope at the Calar Alto
Precision radial velocities of 15 M5-M9 dwarfs

A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU
It is shown that the existence of the planet can be ascertained, and its true mass can be determined with high accuracy, by combining Gaia astrometry and radial velocities, and the candidate planet represents a challenge for the models of super-Earth formation and evolution.
