Abstract

We present optical and near-infrared adaptive optics (AO) imaging and spectroscopy of 13 ultracool (> M6) companions to late-type stars (K7–M4. 5), most of which have recently been identified as candidate members of nearby young moving groups (YMGs; 8–120 Myr) in the literature. Three of these are new companions identified in our AO imaging survey, and two others are confirmed to be comoving with their host stars for the first time. The inferred masses of the companions (~ 10–100 M Jup) are highly sensitive to the ...
