Asymmetry in the protostellar system HOPS 198: Evidence for the evolution of outflow opening angle driven by density of the surrounding core
Donglin Wu, Héctor Arce, Cheng-Han Hsieh
Protostellar outflows are thought to be responsible for the low star formation efficiency of protostellar cores. However, whether outflows can disperse a significant fraction of th…
Preferential alignment of Class 0, Class I protostellar disks in multiple systems across nine nearby molecular clouds
Cheng-Han Hsieh, Aleksey Generozov, Stella S. R. Offner +6
The study examines the orientations of protostellar disks in 512 Class 0, Class I, and flat‑spectrum sources across nine nearby molecular clouds, finding that disks in binary and h…
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…
PROJECT-J: the shocking H2 outflow from HH46
Maria Gabriela Navarro, Brunella Nisini, Teresa Giannini +14
We analyze the H2 emission observed in the HH46 Class I system as part of PROJECT-J (Protostellar Jets Cradle Tested with JWST), to investigate the origin and excitation of the war…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
CAMPOS II. The onset of protostellar disk substructures and planet formation
Cheng-Han Hsieh, Héctor G. Arce, MarÃa José Maureira +6
The 1.3 mm CAMPOS survey has resolved 90 protostellar disks with ~15 au resolution across the Ophiuchus, Corona Australis, and Chamaeleon star-forming regions. To address the funda…
