12 Jul 2003 | | Subject: | astro-ph | | Affiliation: | Astronomy Department, University of Virginia | | Abstract: | The recently discovered, ring-like structure just outside the Galactic disk in Monoceros is detected and traced among 2MASS M giant stars. We have developed a method to recover the signature of this structure from the distance probability density function of stars along a given line of sight. Its detection is possible even when the metallicity is unknown, provided that the structure is not too embedded in the disk. Application of this method reveals the presence of a large group of M giant stars at a Galactocentric distance of 18$pm 2$ kpc, over $+36degr | | Source: | arXiv, astro-ph/0307258 | | Services: | Forum | Review | PDF | Favorites | |
