On the evidence for brown dwarf secondary stars in cataclysmic variables.

LITTLEFAIR S.P., DHILLON V.S. and MARTIN E.L.

Abstract (from CDS):

We present the K -band spectrum of the cataclysmic variable LL And, obtained using NIRSPEC on Keck-II. The spectrum shows no evidence for the absorption features observed by Howell and Ciardi, which these authors used to claim a detection of a brown dwarf secondary star in LL And. In light of our new data, we review the evidence for brown dwarf secondary stars in this and other cataclysmic variables.
