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…
The HH 24 Complex: Jets, Multiple Star Formation, and Orphaned Protostars
Bo Reipurth, J. Bally, Hsi-Wei Yen +9
The HH 24 complex harbors five collimated jets emanating from a small protostellar multiple system. We have carried out a multi-wavelength study of the jets, their driving sources,…
ALMA observations of envelopes around first hydrostatic core candidates
Maria Jose Maureira, Hector G. Arce, Michael M. Dunham +4
We present ALMA 3 mm molecular line and continuum observations with a resolution of ~3.5" towards five first hydrostatic core (FHSC) candidates (L1451-mm, Per-bolo 58, Per-bolo 45,…
Nobeyama 45-m Mapping Observations toward Orion A.I. Molecular Outflows
Yoshihiro Tanabe, Fumitaka Nakamura, Takashi Tsukagoshi +9
We conducted an exploration of 12CO molecular outflows in the Orion A giant molecular cloud to investigate outflow feedback using 12CO (J = 1-0) and 13CO (J = 1-0) data obtained by…
The CARMA-NRO Orion Survey: Core Emergence and Kinematics in the Orion A Cloud
Shuo Kong, Héctor G. Arce, Anneila I. Sargent +19
We have investigated the formation and kinematics of sub-mm continuum cores in the Orion A molecular cloud. A comparison between sub-mm continuum and near infrared extinction shows…
