We have resolved the newly discovered T dwarf SDSS J153417.05+161546.1 into a 011 binary using the Keck sodium laser guide star adaptive optics system. With an integrated-light near-IR spectral type of T3.5 ± 0.5, this binary provides a new benchmark for studying the distinctive J-band brightening previously noted among early and mid-T dwarfs, using two brown dwarfs with different spectral types but having a common metallicity and age and very similar surface gravities. We estimate spectral…

Keck Imaging of Binary L Dwarfs.
TLDR
Keck near-infrared imaging of three binary L dwarf systems indicates that binary companions to L dwarfs are common, that similar-mass systems predominate, and that their distribution peaks at radial distances in accord both with M dwarf binaries and with the radial location of Jovian planets in the authors' own solar system.
