[37.05] An Investigation of the Canis Major Overdensity

W. L. Powell Jr, R. Wilhelm, A. Westfall, A. Lauchner, A. Diaz (Texas Tech University)

Using 2MASS colors Martin et al. (2004) uncovered evidence for a remnant dwarf galaxy in Canis Major, in the form of an overdensity of M-giant stars. The spatial distribution of the M-giants indicate an extended, and likely disrupted, group of stars extending over roughly 30 degrees of the sky. We present new photometry and color magnitude diagrams for various Canis fields. We selected stars corresponding to spectral type A in search of horizontal branch star candidates. We present kinematic results.
