Observational advances over the last decade have enabled high-resolution, interferometric
studies of forming multiple systems, statistical surveys of multiplicity in star-forming regions …

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 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 …

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 the Collection of Elemental Routines for Echelle Spectra (CERES). These
routines were developed for the construction of automated pipelines for the reduction …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

We know little about the outermost exoplanets in planetary systems because our detection
methods are insensitive to moderate-mass planets on wide orbits. However, debris discs …

We characterize the impact of several sources of systematic errors on the computation of the
traceback age of the β Pictoris moving group (βPMG). We find that uncorrected gravitational …

We confirm 66 low-mass stellar and brown dwarf systems (K7–M9) plus 19 visual or
spectroscopic companions of the β Pictoris moving group (BPMG). Of these, 41 are new …

Parameters and abundances have been derived for 1002 stars of spectral types F, G, and K,
and luminosity classes IV and V. After culling the sample for rotational velocity and effective …
