J/MNRAS/385/905 OGLEII high pm stars towards Galactic Centre (Rattenbury+, 2008) ================================================================================ OGLE-II high proper motion stars towards the Galactic Centre. Rattenbury N.J., Mao S. =2008MNRAS.385..905R ================================================================================ ADC_Keywords: Stars, nearby ; Proper motions ; Photometry, infrared ; Stars, distances Keywords: stars: distances - stars: statistics - solar neighbourhood Abstract: The photometry data base of the second phase of the OGLE microlensing experiment, OGLE-II, is a rich source of information about the kinematics and structure of the Galaxy. In this work, we use the OGLE-II proper motion catalogue to identify candidate stars which have high proper motions. 521 stars with proper motion {mu}>50mas/yr in the OGLE-II proper motion catalogue were cross-identified with stars in the MACHO high proper motion catalogue, and the DEep Near-Infrared Survey and Two-Micron All-Sky Survey infrared photometry catalogues. Photometric distances were computed for stars with colours consistent with G/K- and M-type stars. Six stars were newly identified as possible nearby (<50pc) M dwarfs.
