Abstract (from CDS):

We report deep imaging observations of the young, nearby star ABPic, a member of the large Tucana-Horologium association. We have detected a faint, red source 5.5'' South of the star with JHK colors compatible with that of a young substellar L dwarf. Follow-up observations at two additional epochs confirm, with a confidence level of 4.7σ, that the faint red object is a companion to ABPic rather than it being a stationary background object. A low resolution K-band spectrum indicates an early-L spectral type for the companion. Finally, evolutionary model predictions based on the JHK photometry of ABPicb indicate a mass of 13 to 14MJup if its age is ∼30Myr. Is ABPicb a massive planet or a minimum mass brown dwarf?
