The Co-evolution of Disk and Star in Embedded Stages: The Case of the Very Low-mass Protostar
Yuki Okoda, Yoko Oya, Nami Sakai +4
We have observed the CCH (N=3-2, J=7/2-5/2, F=4-3 and 3-2) and SO (6_7-5_6) emission at a 0"2 angular resolution toward the low-mass Class 0 protostellar source IRAS 15398-3359 wit…
Rotation in the NGC 1333 IRAS 4C Outflow
Yichen Zhang, Aya E. Higuchi, Nami Sakai +8
We report molecular line observations of the NGC 1333 IRAS 4C outflow in the Perseus Molecular Cloud with the Atacama Large Millimeter/Submillimeter Array. The CCH and CS emission…
Sub-arcsecond Kinematic Structure of the Outflow in the Vicinity of the Protostar in L483
Yoko Oya, Nami Sakai, Yoshimasa Watanabe +4
The bipolar outflow associated with the Class 0 low-mass protostellar source (IRAS 18148-0440) in L483 has been studied in the CCH and CS line emission at 245 and 262 GHz, respecti…
Chemical survey toward young stellar objects in the Perseus molecular cloud complex
Aya E. Higuchi, Nami Sakai, Yoshimasa Watanabe +12
Chemical diversity of the gas in low-mass protostellar cores is widely recognized. In order to explore its origin, a survey of chemical composition toward 36 Class 0/I protostars i…
Seeds of Life in Space (SOLIS). III. Zooming into the methanol peak of the pre-stellar core L1544
Anna Punanova, Paola Caselli, Siyi Feng +41
Towards the pre-stellar core L1544, the methanol (CHOH) emission forms an asymmetric ring around the core centre, where CHOH is mostly in solid form, with a clear peak 4000…
Chemical and Physical Picture of IRAS 16293-2422 Source B at a Sub-arcsecond Scale Studied with ALMA
Yoko Oya, Kana Moriwaki, Shusuke Onishi +7
We have analyzed the OCS, HCS, CHOH, and HCOOCH data observed toward the low-mass protostar IRAS 16293--2422 Source B at a sub-arcsecond resolution with ALMA. A clear c…
