Slicing the monoceros overdensity with suprime-cam
We derive distance, density, and metallicity distribution of the stellar Monoceros Overdensity (MO) in the outer Milky Way, based on deep imaging with the Subaru Telescope. We applied color-magnitude diagram fitting techniques in three stripes at galactic longitudes, l 130°, 150°, 170°, and galactic latitudes, +15° ≤ b ≤ +25°. The MO appears as a wall of stars at a heliocentric distance of 10.1 ± 0.5kpc across the observed longitude range with no distance change. The MO stars are more...[Show more]
