The trigonometric parallax of DENIS-P J104814.7-395606.1.

DEACON N.R. and HAMBLY N.C.

Abstract (from CDS):

We present a measurement of the trigonometric parallax for a nearby very low mass star recently discovered by Delfosse et al. (2001A&A...366L..13D). Using schmidt plates measured on the SuperCOSMOS plate scanning machine we find a parallax of π=192±37mas, giving a distance of d=5.2+1.2–0.8pc. Using this distance we find the absolute magnitude and kinematics for the object to be consistent with an intermediate-age disk object of mass 0.08M. This star is clearly nearby and is on these measurements between the 30th and 86th closest known stellar system to the Sun; it could be the closest M9 dwarf to the Sun.
