cds-question@unistra.frstellar-associationsm-starsproper-motionsstellar-distanceradial-velocityinfrared-photometryx-ray-sourcesWe present a new method based on a Bayesian analysis to identify new members of nearby young kinematic groups. The analysis minimally takes into account the position, proper motion, magnitude, and color of a star, but other observables can be readily added (e.g., radial velocity, distance). We use this method to find new young low-mass stars in the {beta} Pictoris and AB Doradus moving groups and in the TW Hydrae, Tucana-Horologium, Columba, Carina, and Argus associations. Starting from a sample of 758 mid-K to mid-M (K5V-M5V) stars showing youth indicators such as H{alpha} and X-ray emission, our analysis yields 214 new highly probable low-mass members of the kinematic groups analyzed. One is in TW Hydrae, 37 in {beta} Pictoris, 17 in Tucana-Horologium, 20 in Columba, 6 in Carina, 50 in Argus, 32 in AB Doradus, and the remaining 51 candidates are likely young but have an ambiguous membership to more than one association. The false alarm rate for new candidates is estimated to be 5% for {beta} Pictoris and TW Hydrae, 10% for Tucana-Horologium, Columba, Carina, and Argus, and 14% for AB Doradus. Our analysis confirms the membership of 58 stars proposed in the literature. Firm membership confirmation of our new candidates will require measurement of their radial velocity (predicted by our analysis), parallax, and lithium 6708{AA} equivalent width. We have initiated these follow-up observations for a number of candidates, and we have identified two stars (2MASSJ01112542+1526214, 2MASSJ05241914-1601153) as very strong candidate members of the {beta} Pictoris moving group and one strong candidate member (2MASSJ05332558-5117131) of the Tucana-Horologium association; these three stars have radial velocity measurements confirming their membership and lithium detections consistent with young age.2013ApJ...762...88Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/762/88CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/272 : RAVE 4th data release (Kordopatis+, 2013)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)V/137 : Extended Hipparcos Compilation (XHIP) (Anderson+, 2012)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/317 : The PPMXL Catalog (Roeser+ 2010)III/254 : 2nd Cat. of RVs with Astrometric Data (Kharchenko+, 2007)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)III/252 : Pulkovo radial velocities for 35493 HIP stars (Gontcharov, 2006)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/259 : The Tycho-2 Catalogue (Hog+ 2000)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/ApJ/758/56 : Young M dwarfs within 25pc.
