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 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) …

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 derive the bolometric luminosities (L bol) of 865 field-age and 189 young ultracool
dwarfs (spectral types M6–T9, including 40 new discoveries presented here) by directly …

We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine
these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of the …

Young stellar associations hold a star formation record that can persist for millions of years,
revealing the progression of star formation long after the dispersal of the natal cloud. To …

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 …

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 …

We present a survey for photometric variability in young, low-mass brown dwarfs with the
Spitzer Space Telescope. The 23 objects in our sample show robust signatures of youth and …
