Astronomers have discovered thousands of planets outside the Solar System, most of which
orbit stars that will eventually evolve into red giants and then into white dwarfs. During the …

We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager
Exoplanet Survey. This subsample includes six detected planets and three brown dwarfs; …

BANYAN Σ is a new Bayesian algorithm to identify members of young stellar associations
within 150 pc of the Sun. It includes 27 young associations with ages in the range∼ 1–800 …

The mass–luminosity relation for late-type stars has long been a critical tool for estimating
stellar masses. However, there is growing need for both a higher-precision relation and a …

Aims. We study the evolution of the rotation and the high energy X-ray, extreme ultraviolet
(EUV), and Ly-α emission for F, G, K, and M dwarfs, with masses between 0.1 and 1.2 M⊙ …

Precise and accurate parameters for late-type (late K and M) dwarf stars are important for
characterization of any orbiting planets, but such determinations have been hampered by …

Context. The relevance of M dwarfs in the search for potentially habitable Earth-sized
planets has grown significantly in the last years. Aims. In our on-going effort to …

The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any
orbiting planets. In this paper, we present the survey sample by publishing one CARMENES …

The high-energy emission from low-mass stars is mediated by the magnetic dynamo.
Although the mechanisms by which fully convective stars generate large-scale magnetic …

Aims. We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES
survey. This is the first time that such a large and homogeneous high-resolution (R> 80 000) …
