A VERY HIGH PROPER MOTION STAR AND THE FIRST L DWARF IN THE KEPLER FIELD

A VERY HIGH PROPER MOTION STAR AND THE FIRST L DWARF IN THE KEPLER FIELD

We report two nearby high proper motion dwarfs of special interest identified using the Preliminary Data Release of the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All Sky Survey. WISEP J191239.91--361516.4 has a motion of 2.1 arcsec yr--1. Photometry identifies it as a mid-M dwarf...

Zusammenfassung:We report two nearby high proper motion dwarfs of special interest identified using the Preliminary Data Release of the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All Sky Survey. WISEP J191239.91--361516.4 has a motion of 2.1 arcsec yr--1. Photometry identifies it as a mid-M dwarf. WISEP J190648.47+401106.8 is a spectroscopically confirmed L1 dwarf in the Kepler Mission field with a motion of 0.48 arcsec yr--1. The estimated distance is 17 pc. Both lie at relatively low galactic latitudes and demonstrate the possibility of discovering proper motion stars independent of the historic photographic sky surveys.
