Spectroscopic distances of nearby ultracool dwarfs.

PHAN-BAO N. and BESSELL M.S.

Abstract (from CDS):

We present updated results of spectroscopic follow-up observations of a sample of 45 M dwarf candidates identified by Phan-Bao et al. (2003A&A...401..959P) based on the DENIS photometry and proper motion measurements. Forty one of these are nearby late-M dwarfs (d<30pc) with spectral types ranging from M5.0 to M8.5 computed from the spectral indices. One contaminant is probably an F-G main sequence star reddened by intervening dust and three stars that were not observed have previous classifications as M dwarfs in the literature. In this paper, we identify three M7.5, five M8.0, one M8.5 dwarf and confirm two new M8.0 dwarf members of the 25pc volume.
