Abstract
Widely-separated (≳100 au) multiples are rare among the lowest mass stars and brown dwarfs (Caballero 2007; Kraus & Hillenbrand 2009), and often (but not exclusively) associated with young (≾100 Myr), nearby stellar associations (e.g., Close et al. 2007). We report the discovery of a wide, very low mass, and potentially young binary, 2MASS J14504216–7841413 and 2MASS J14504113–7841383 (hereafter 2MASS J1450–7841AB). The primary was initially identified in the DENIS (Epchtein et al. 1997) and 2MASS (Skrutskie et al. 2006) surveys as a candidate late-M dwarf based on its red optical/infrared colors (DENIS I = 18.03 ± 0.16, I − J = 3.32 ± 0.19, 2MASS J = 14.71 ± 0....
