Context. Teegarden's Star is the brightest and one of the nearest ultra-cool dwarfs in the
solar neighbourhood. For its late spectral type (M7. 0 V), the star shows relatively little …

Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than
gas giants around low-mass stars, as predicted by the core accretion theory of planet …

We present the discovery of an Earth-mass planet (M b sin i= 1.26±0.21 M⊕) on a 15.6 d
orbit of a relatively nearby (d~ 9.6 pc) and low-mass (0.167±0.011 M⊙) M5. 0 V star, Wolf …

We report the discovery and characterisation of two Earth-mass planets orbiting in the
habitable zone of the nearby M-dwarf GJ 1002 based on the analysis of the radial-velocity …

We announce the discovery of two planets orbiting the M dwarfs GJ 251 (0.360±0.015M⊙)
and HD 238090 (0.578±0.021M⊙) based on CARMENES radial velocity (RV) data. In …

The catalogue contains 199 confirmed cases of binary systems containing at least one
pulsating component of δ Sct type. The sample is divided into subgroups in order to describe …

The CARMENES radial-velocity survey is currently searching for planets in a sample of 387
M dwarfs. Here we report on two Saturn-mass planets orbiting TYC 2187-512-1 (M*= 0.50 …

Context. The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three
planets, and a fourth tentative signal. The orbital period of each planet is the subject of …

Context. Variability caused by stellar activity represents a challenge to the discovery and
characterization of terrestrial exoplanets and complicates the interpretation of atmospheric …

We present Kepler satellite photometry of KIC 10661783, a short-period binary star system
which shows total eclipses and multiperiodic δ Scuti pulsations. A frequency analysis of the …
