Characterization of the Young Galactic Star Cluster Stock 2 with 2MASS, PPMXL, and Pan-STARRS Data

We study the astrometry and photometry in the field of Stock 2, a rich and nearby star cluster. Using PPMXL proper motions, and 2MASS plus Pan-STARRS photometry, we identified a reliable list of members, with which a distance of 300 pc, an age of 5.6(+3.3/-2.8) Myr, and a reddening E(B-V)= 0.3 were derived. Member candidates with masses < 0.15 solar, i.e., close to the hydrogen-burning limit, are also selected. We present the stellar mass function and possible mass segregation of this very young cluster.
