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…

The ALMA Legacy survey of Class 0/I disks in Corona australis, Aquila, chaMaeleon, oPhiuchus north, Ophiuchus, Serpens (CAMPOS). I. Evolution of Protostellar disk radii

Cheng-Han Hsieh, Héctor G. Arce, María José Maureira +5

We surveyed nearly all the embedded protostars in seven nearby clouds (Corona Australis, Aquila, Chamaeleon I & II, Ophiuchus North, Ophiuchus, Serpens) with the Atacama Large Mill…

The Evolution of Protostellar Outflow Cavities, Kinematics, and Angular Distribution of Momentum and Energy in Orion A: Evidence for Dynamical Cores

Cheng-Han Hsieh, Héctor G. Arce, Zhi-Yun Li +13

We present Atacama Large Millimeter/submillimeter Array observations of the 10 kAU environment surrounding 21 protostars in the Orion A molecular cloud tracing outflows. Our…
