Keck laser guide star adaptive optics monitoring of 2MASS j15344984-2952274ab: First dynamical mass determination of a binary T dwarf

Liu, Michael C; Dupuy, Trent J; Ireland, Michael

Description

We present multiepoch imaging of the T5.0+T5.5 binary 2MASS J15344984-2952274AB obtained with the Keck laser guide star adaptive optics system. Combined with archival HST imaging, our total data span ̃50% of the orbital period. We use a Markov chain Mont
