Protostar L1455 IRS1: Rotating Disk Connecting to Filamentary Network
Hsuan-Gu Chou, Hsi-Wei Yen, Patrick M. Koch +1
We conducted IRAM-30m C18O (2-1) and SMA 1.3mm continuum, 12CO (2-1), and C18O (2-1) observations toward the Class 0/I protostar L1455 IRS1 in Perseus. The IRAM results show L1455…
Local Magnetic Field Role in Star Formation
Patrick M. Koch, Ya-Wen Tang, Paul T. P. Ho +14
We highlight distinct and systematic observational features of magnetic field morphologies in polarized submm dust continuum. We illustrate this with specific examples and show sta…
High-resolution CO observation of the carbon star CIT 6 revealing the spiral structure and a nascent bipolar outflow
Hyosun Kim, Sheng-Yuan Liu, Naomi Hirano +8
CIT 6 is a carbon star in the transitional phase from the asymptotic giant branch (AGB) to the protoplanetary nebulae (pPN). Observational evidences of two point sources in the opt…
No Keplerian Disk >10 AU around the Protostar B335: Magnetic Braking or Young Age?
Hsi-Wei Yen, Shigehisa Takakuwa, Patrick M. Koch +4
We have conducted ALMA cycle 2 observations in the 1.3 mm continuum and in the C18O (2-1) and SO (5_6-4_5) lines at a resolution of ~0.3" toward the Class 0 protostar B335. The 1.3…
ALMA Observations of the Transition from Infall Motion to Keplerian Rotation around the Late-phase Protostar TMC-1A
Yusuke Aso, Nagayoshi Ohashi, Kazuya Saigo +9
We have observed the Class I protostar TMC-1A with Atacama Millimeter/submillimeter Array (ALMA) in 12CO and C18O (J=2-1), and 1.3-mm dust continuum emission. Continuum emission wi…
