An ALMA Constraint on the GSC 6214-210 B Circum-substellar Accretion Disk Mass
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of GSC 6214-210 A and B, a solar-mass member of the 5-10 Myr Upper Scorpius association with a 15 ± 2 M<inf>Jup</inf> companion orbiting at ≈330 AU (2.″2). Previous photometry and spectroscopy spanning 0.3-5 μm revealed optical and thermal excess as well as strong H and Pa β emission originating from a circum-substellar accretion disk around GSC 6214-210 B, making it the lowest-mass companion with unambiguous evidence...[Show more]
