Temperature Structure of the Pipe Nebula Studied by the Intensity Anomaly of the OH 18 cm
Yuji Ebisawa, Nami Sakai, Karl M. Menten +2
We present observations of the four hyperfine structure components of the OH 18 cm transition (1612, 1665, 1667 and 1720 MHz) toward a filamentary dark cloud, the Pipe nebula, with…
Substructures in the Disk-Forming Region of the Class 0 Low-Mass Protostellar Source IRAS 16293-2422 Source A on a 10 au Scale
Yoko Oya, Satoshi Yamamoto
We have observed the Class 0 protostellar source IRAS 16293-2422 A in the C17O and H2CS lines as well as the 1.3 mm dust continuum with the Atacama Large Millimeter/submillimeter A…
ALMA resolves the remarkable molecular jet and rotating wind in the extremely radio-quiet galaxy NGC 1377
S. Aalto, N. Falstad, S. Muller +14
Submillimetre and millimetre observations are important in probing the properties of the molecular gas and dust around obscured active galactic nuclei (AGNs) and their feedback. Wi…
Molecular Distributions of the Protostellar Envelope and the Outflow of IRAS 15398-3359: Principal Component Analysis
Yuki Okoda, Yoko Oya, Nami Sakai +2
We have imaged 15 molecular-line emissions and the dust continuum emission around the Class 0 protostellar source, IRAS 15398-3359, with ALMA. The outflow structure is mainly trace…
FAUST I. The hot corino at the heart of the prototypical Class I protostar L1551 IRS5
E. Bianchi, C. J. Chandler, C. Ceccarelli +63
The study of hot corinos in Solar-like protostars has been so far mostly limited to the Class 0 phase, hampering our understanding of their origin and evolution. In addition, recen…
Search for Alignment of Disk Orientations in Nearby Star-Forming Regions: Lupus, Taurus, Upper Scorpius, Ophiuchi, and Orion
Masataka Aizawa, Yasushi Suto, Yoko Oya +2
Spatial correlations among proto-planetary disk orientations carry unique information on physics of multiple star formation processes. We select five nearby star-forming regions th…
