Abstract:
BANYAN Σ is a new Bayesian algorithm to identify members of
young stellar associations within 150pc of the Sun. It includes 27
young associations with ages in the range ∼1-800Myr, modeled with
multivariate Gaussians in six-dimensional (6D) XYZUVW space. It is the
first such multi-association classification tool to include the
nearest sub-groups of the Sco-Cen OB star-forming region, the IC2602,
IC2391, Pleiades and Platais 8 clusters, and the ρ Ophiuchi,
Corona Australis, and Taurus star formation regions. A model of field
stars is built from a mixture of multivariate Gaussians based on the
Besancon Galactic model. The algorithm can derive membership
probabilities for objects with only sky coordinates and proper motion,
but can also include parallax and radial velocity measurements, as
well as spectrophotometric distance constraints from sequences in
color-magnitude or spectral type-magnitude diagrams. BANYAN Σ
benefits from an analytical solution to the Bayesian marginalization
integrals over unknown radial velocities and distances that makes it
more accurate and significantly faster than its predecessor BANYAN II.
A contamination versus hit rate analysis is presented and demonstrates
that BANYAN Σ achieves a better classification performance than
other moving group tools available in the literature, especially in
terms of cross-contamination between young associations. An updated
list of bona fide members in the 27 young associations, augmented by
the Gaia-DR1 release, as well as all parameters for the 6D
multivariate Gaussian models for each association and the Galactic
field neighborhood within 300 pc are presented.
