YNMGs could be the result of the recent dispersal of young embedded clusters, such that they still represent kinematically cold groups, carrying the residual motion of their parental cloud. Using the fact that a large number (~14000) of the RAVE sources with evidence of chromospheric activity also present signatures of stellar youth, we selected a sample of solar-type sources with the highest probability of chromospheric activity to look for common kinematics. We made use of radial velocity information from RAVE and astrometric parameters from GAIA DR2 to construct a 6D position-velocity vector catalog for our full sample. We developed a method based on the grouping of stars with similar orientation of their velocity vectors, which we call the Cone Method Sampling. Using this method, we detected 646 sources with high significance in the velocity space, with respect to the average orientation of artificial distributions made from a purely Gaussian velocity ellipsoid with null vertex deviation. We compared this sample of highly significant sources with a catalog of YNMGs reported in previous studies, which yield 75 confirmed members. From the remaining sample, about 50% of the sources have ages younger than 100Myr, which indicate they are highly probable candidates to be new members of identified or even other YNMGs in the solar neighborhood.2018ApJ...867...93Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/867/93CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)III/279 : RAVE 5th data release (Kunder+, 2017)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer- Jones+, 2018)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/other/ARA+A/42.685 : Young stars near the Sun (Zuckerman+, 2004)J/AJ/130/188 : Young stars in Trumpler 37 & NGC7160 (Sicilia- Aguilar+, 2005)J/A+A/460/695 : Search for Associations Containing Young stars (Torres+, 2006)J/A+A/508/833 : SACY III.
