THE HYPERACTIVE L DWARF 2MASS J13153094–2649513: CONTINUED EMISSION AND A BROWN DWARF COMPANION

We report new observations of the unusually active, high proper motion L5e dwarf 2MASS J13153094–2649513. Optical spectroscopy with Magellan/MagE reveals persistent nonthermal emission, with narrow H I Balmer, Na I and K I lines all observed in emission. Low-resolution near-infrared spectroscopy wit...
