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
Protostellar disk orientations in multiple systems provide critical insights into the primary mechanisms that govern the formation of multiple-star systems, their subsequent dynami…
ALMA High-resolution Observation of the HH46/47 Outflow/disk/envelope System
Heyi Zhang, Yichen Zhang, Héctor G. Arce +5
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, María 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…
HH 270/110 as a jet/shear layer interaction
A. C. Raga, A. Noriega-Crespo, A. Castellanos-Ramirez +5
New observations obtained with JWST of the proto-stellar HH~270 jet and the "deflected" HH 110 system, show that HH 110 has a morphology of a series of distorted working surfaces.…
The Evolution of Protostellar Outflow Opening Angles and the Implications for the Growth of Protostars
Michael M. Dunham, Ian W. Stephens, Philip C. Myers +5
We use 1-4" (300-1200 au) resolution 12CO(2-1) data from the MASSES (Mass Assembly of Stellar Systems and their Evolution with the SMA) project to measure the projected opening ang…
The protostars in Orion: Characterizing the properties of their magnetized envelopes
B. Huang, J. M. Girart, I. W. Stephens +17
We present a study connecting the physical properties of protostellar envelopes to the morphology of the envelope-scale magnetic field. We used the ALMA polarization observations o…
