DENIS J081730.0−615520 (also known as 2MASS 08173001−6155158) is a T-type brown dwarf Шаблон:Convert away in the constellation Carina. It was discovered by Etienne Artigau and his colleagues in April 2010.[1] The brown dwarf belongs to the T6 spectral class, with a photosphere temperature of about 1000 K.[2] It has a mass of about 15 MJ (Jupiter masses) or about 1.5% the mass of the Sun.Шаблон:Failed verification

DENIS J081730.0-615520 is the fourth-nearest isolated T dwarf to the Sun (after UGPS J0722−0540, WISE 1741+2553, and WISE 1506+7027) and the eighth-nearest (also after Luhman 16B, ε Indi Bab and SCR 1845-6357B) if one takes into account T dwarfs in multiple star systems.[3] It is also the brightest T dwarf in the sky (in the J-band); it had been missed before due to its proximity to the galactic plane.[1]
