Absolute Properties of the Low-Mass Eclipsing Binary CM Draconis
Spectroscopic and eclipsing binary systems offer the best means for determining accurate physical properties of stars, including their masses and radii. The data available for low-mass stars have
Distance and Kinematics of the TW Hydrae Association from Parallaxes
From common proper motion and signatures of youth, researchers have identified about 30 members of a putative TW Hydrae Association. Only four of these had parallactic distances from Hipparcos. We
The HARPS-TERRA Project. I. Description of the Algorithms, Performance, and New Measurements on a Few Remarkable Stars Observed by HARPS
Doppler spectroscopy has uncovered or confirmed all the known planets orbiting nearby stars. Two main techniques are used to obtain precision Doppler measurements at optical wavelengths. The first
A planetary system around the nearby M dwarf GJ 667C with at least one super-earth in its habitable zone
We re-analyze 4 years of HARPS spectra of the nearby M1.5 dwarf GJ 667C available through the European Southern Observatory public archive. The new radial velocity (RV) measurements were obtained
The habitability of Proxima Centauri b II. Possible climates and Observability
Radial velocity monitoring has found the signature of a $M \sin i = 1.3$~M$_\oplus$ planet located within the Habitable Zone (HZ) of Proxima Centauri \citep{Anglada16}. Despite a hotter past and an
Trigonometric Parallaxes and Proper Motions of 134 Southern Late M, L, and T Dwarfs from the Carnegie Astrometric Planet Search Program
We report trigonometric parallaxes for 134 low mass stars and brown dwarfs, of which 38 have no previously published measurement and 79 more have improved uncertainties. Our survey targeted nearby
A dynamically-packed planetary system around GJ 667C with three super-Earths in its habitable zone
Guillen Anglada-Escude, et al, 'A dynamically-packed planetary system around GJ 667J with three super-Earths in its habitable zone', A&A, Vol. 556, A126, first published online 7 August 2013. The
GJ 1214 reviewed - Trigonometric parallax, stellar parameters, new orbital solution, and bulk properties for the super-Earth GJ 1214b
Context. GJ 1214 is orbited by a transiting super-Earth-mass planet. It is a primary target for ongoing efforts to understand the emerging population of super-Earth-mass planets around M dwarfs, some
Two planets around Kapteyn's star: a cold and a temperate super-Earth orbiting the nearest halo red dwarf
Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of Kapteyn's star, which is
