Monitoring Hα Emission from the Wide-orbit Brown-dwarf Companion FU Tau B

Monitoring mass accretion onto substellar objects provides insights into the geometry of the accretion flows. We use the Lulin One-meter Telescope to monitor H α emission from FU Tau B, a ∼19 M _Jup brown-dwarf companion at 5.″7 (719 au) from the host star, for six consecutive nights. This is the lo...
