A 2MASS survey for brown dwarfs toward the Hyades.

Abstract (from CDS):

We present results of a search for very low mass stars and brown dwarfs toward the central region of the Hyades. Using Two Micron All Sky Survey (2MASS) near-infrared and Second Palomar Sky Survey (POSS II) optical photometry, we select candidates corresponding to spectral types M8-L4 at the distance of the Hyades. Spectroscopic follow-up data indicate that none are cluster members. The lack of members in the mass range 0.08 M<M<0.06 M is consistent with evidence that this 600 Myr-old cluster is deficient in very low mass objects. Three of our objects are of spectral type M8, with surface gravity-sensitive features intermediate between dwarfs and giants. We interpret these objects as background brown dwarfs, perhaps associated with the Taurus star formation region.
