Serendipitous discovery of seven new southern L-dwarfs.

KENDALL T.R., MAURON N., AZZOPARDI M. and GIGOYAN K.

Abstract (from CDS):

We report the discovery of seven hitherto unknown L-dwarfs found as a result of a spectroscopic search for distant AGB stars. Their far-red and near-infrared colours are very similar to known dwarfs of the same spectral type. One new object is among the ∼30 brightest L-dwarfs, with Ks=12.12, and is nearby, ∼20pc. Using low resolution spectroscopy from the Danish 1.54m ESO telescope, spectral types in the range L0.5-L5 are derived for these seven L-dwarfs by direct comparison to L-type standards taken from Kirkpatrick et al. (1999ApJ...519..802K). Distances are determined from existing calibrations, and together with measured proper motions, yield kinematics for the seven new dwarfs consistent with that expected for the solar neighbourhood disk population.
