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 …

We present an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar
model and isochrone library for a solar-scaled heavy element distribution. The main input …

Context. The publication of the Gaia Data Release 2 (Gaia DR2) opens a new era in
astronomy. It includes precise astrometric data (positions, proper motions, and parallaxes) …

Aims. Within a 200 pc sphere around the Sun, we search for the Hyades tidal tails in the
Gaia DR2 dataset. Methods. We used a modified convergent-point method to search for …
