Gas flow and accretion via spiral streamers and circumstellar disks in a young binary protostar

Caselli, P.; Segura-Cox, D.; Zhao, B. +4 more

The majority of stars are part of gravitationally bound stellar systems, such as binaries. Observations of protobinary systems constrain the conditions that lead to stellar multiplicity and subsequent orbital evolution. We report high-angular resolution observations of the circumbinary disk around [BHB2007] 11, a young binary protostar system. The…
