1307.1127 (Jonathan Gagné et al.)

Bayesian analysis to identify very low-mass members of nearby young stellar kinematic groups    [PDF]

Jonathan Gagné, David Lafrenière, René Doyon, Lison Malo, Jacqueline Faherty, Étienne Artigau
We describe our all-sky survey for >M4 candidate members to nearby, young associations from the 2MASS and WISE catalogs using bayesian inference. We report the first results, including 38 highly probable candidates showing spectroscopic signs of low-gravity (and thus youth). The latest of these objects would correspond to a 11 - 13 MJup object, around the limit of the planetary regime.
