ALMA High-resolution Observation of the HH46/47 Outflow/disk/envelope System
Heyi Zhang, Yichen Zhang, Héctor G. Arce +6
We present ( au) resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the HH 46/47 molecular outflow and its envelope-disk s…
The Keplerian disk, envelope, and streamers surrounding an early O-type protostar in the Sagittarius C cloud of the Central Molecular Zone
Jixiang Weng, Xing Lu, Yu Cheng +22
Disk-mediated accretion is central to theories of massive star formation, setting the initial conditions for their evolution. Yet observations of Keplerian disks around early O-typ…
Dense Molecular Ring-like structure in gaseous CO depletion region G34.74-0.12
Shuting Lin, Siyi Feng, Fengwei Xu +14
We report the discovery of a dense molecular ring-like structure in a dense (10 cm), cold (pc-scale CO depletion at a factor of 5), and young (10 year) star-forming…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). XII. Unanchored Forked Stream in the Propagating Path of a Protostellar Outflow
Shuting Lin, Siyi Feng, Patricio Sanhueza +14
Outflows are key indicators of ongoing star formation. We report the discovery of an unanchored forked stream within the propagating path of an extremely young protostellar outflow…
