Abstract (from CDS):

We report the discovery of LSR 1826+3014, a very faint (V=19.36) star with a very large proper motion (µ=2".38 yr–1). A low-resolution red spectrum reveals that LSR 1826+3014 is an ultracool red dwarf with spectral type M8.5 V and with a radial velocity vrad=+77±10 km.s–1. LSR 1826+3014 is thus the faintest red dwarf ever discovered with a proper motion larger than 2" yr–1. Optical and infrared photometry suggest that the star is at a distance d=13.9±3.5 pc from the Sun, which implies that it is moving relative to the local standard of rest with a total velocity of 175±25 km .s–1. The numerical integration of its orbit suggests that LSR 1826+3014 is on a halo-like Galactic orbit.
