}We report the first comprehensive study of emission-line variability in an accreting young brown dwarf. We have collected 14 high-resolution optical spectra of 2MASSW J1207334-393254 (M8), a likely member of the nearby 8 million year old TW Hydrae association with a recently identified planetary mass companion, in three observing runs between 2005 January-March on the Magellan Clay telescope. These spectra show a variety of emission lines that are commonly seen in classical T Tauri stars. The H… CONTINUE READING
