Descripción
We present the discovery of a 14-8+2 MJup
companion located at 670 AU from UScoC-TIO 108, a 60+/-20 MJup brown
dwarf of the very young Upper Scorpius association. Optical and
near-infrared photometry and spectroscopy confirm that both the primary
and secondary are very cool objects, with Teff of 2700 and 2100 K,
respectively, and that they are bona fide young members of the
association. We will discuss the implications of the existence of wide
substellar companions in current models of formation of these very
low-mass objects. The results of this proceeding is also published in
Béjar et al. 2008, ApJ, 673, L185.
