  • We discover that the very low-mass brown dwarf OTS 44 (M9.5, similar to 12 M-Jup) has significant accretion and a substantial disk, which demonstrates that the processes that accompany canonical star formation occur down to a central mass of a few Jupiter masses. We discover in VLT/SINFONI spectra that OTS 44 has strong, broad, and variable Pa beta emission that is evidence for active accretion at the planetary border. We also detect strong Ha emission of OTS 44 in a literature spectrum and… CONTINUE READING
