Characterization of a young open cluster G144.9+0.4 in Cam OB1 Available to Purchase

Open clusters are good laboratories to study stellar evolution and dynamical interaction among member stars. We are carrying out a program to identify uncharted clusters using sky-survey data. Our preliminary result is finding stellar density enhancement using the 2MASS Point Source Catalog in Galactic latitude |b| < 50 deg. One such density peak (G144.9+0.4), located in the Cam OB1 association, is a young star cluster centered at (ℓ,b) = (144.904,+0.434), first recognized but not well characterized, by Glushkova et al. [8]. We used the PPMXL proper motions to constrain the membership. Our analysis yields a distance of 1.0 kpc. G144.9+0.4 is hence physically related to the Cam OB1 association. Based on the 2MASS and WISE colors, seven classical T-Tauri Star candidates are found within the cluster, though, three of these have proper motions inconsistent with members. One of the kinematic members has been confirmed by spectroscopy to be a CTTS.
