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 …

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 …

We present a self-consistent, absolute isochronal age scale for young (≲ 200 Myr), nearby
(≲ 100 pc) moving groups in the solar neighbourhood based on homogeneous fitting of …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

Rotation is a directly observable stellar property, and it drives magnetic field generation and
activity through a magnetic dynamo. Main-sequence stars with masses below approximately …

We present results of the largest, most comprehensive study ever done of the stellar
multiplicity of the most common stars in the Galaxy, the red dwarfs. We have conducted an …

Context. The β Pictoris moving group is one of the most well-known young associations in
the solar neighbourhood and several members are known to host circumstellar discs …

Mature super-Earths and sub-Neptunes are predicted to be≃ Jovian radius when younger
than 10 Myr. Thus, we expect to find 5–15 R⊕ planets around young stars even if their older …

CARMENES is a spectrograph for radial velocity surveys of M dwarfs with the aim of
detecting Earth-mass planets orbiting in the habitable zones of their host stars. To ensure an …
