Dust polarized emission observations of NGC 6334; BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
D. Arzoumanian, R. Furuya, T. Hasegawa +145
[Abridged] Filaments and hubs have received special attention recently thanks to studies showing their role in star formation. While the column density and velocity structures of b…
Dynamical stellar masses of pre-main sequence stars in Lupus and Taurus obtained with ALMA surveys in comparison with stellar evolutionary models
Teresa A. M. Braun, Hsi-Wei Yen, Patrick M. Koch +3
We analysed archival molecular line data of pre-main sequence (PMS) stars in the Lupus and Taurus star-forming regions obtained with ALMA surveys with an integration time of a few…
Observations of magnetic fields surrounding LkH 101 taken by the BISTRO survey with JCMT-POL-2
Nguyen Bich Ngoc, Pham Ngoc Diep, Harriet Parsons +146
We report the first high spatial resolution measurement of magnetic fields surrounding LkH 101, a part of the Auriga-California molecular cloud. The observations were taken with…
The JCMT BISTRO survey: alignment between outflows and magnetic fields in dense cores/clumps
Hsi-Wei Yen, Patrick M. Koch, Charles L. H. Hull +43
We compare the directions of molecular outflows of 62 low-mass Class 0 and I protostars in nearby (<450 pc) star-forming regions with the mean orientations of the magnetic fields o…
Kinematical signs of dust trapping and feedback in a local pressure bump in the protoplanetary disk around HD 142527 revealed with ALMA
Hsi-Wei Yen, Pin-Gao Gu
We analyzed the archival data of the continuum emission at six wavelengths from 3 to 0.4 mm and 13CO and C18O (1-0, 2-1, and 3-2) lines in the protoplanetary disk around HD 142527…
The JCMT BISTRO Survey: Magnetic Fields Associated with a Network of Filaments in NGC 1333
Yasuo Doi, Tetsuo Hasegawa, Ray S. Furuya +135
We present new observations of the active star-formation region NGC 1333 in the Perseus molecular cloud complex from the James Clerk Maxwell Telescope B-Fields In Star-forming Regi…
Circumbinary Disks of the Protostellar Binary Systems in the L1551 Region
Shigehisa Takakuwa, Kazuya Saigo, Tomoaki Matsumoto +6
We report ALMA Cycle 4 observations of the Class I binary protostellar system L1551 IRS 5 in the 0.9-mm continuum emission, C18O (J=3-2), OCS (J=28-27), and four other Band 7 lines…
Disk structure around the Class I protostar L1489 IRS revealed by ALMA: a warped disk system
Jinshi Sai, Nagayoshi Ohashi, Kazuya Saigo +9
We have observed the Class I protostar L1489 IRS with the Atacama Millimeter/submillimeter Array (ALMA) in Band 6. The CO 2-1 line emission shows flattened and non-axisy…
Transition from ordered pinched to warped magnetic field on a 100 au scale in the Class 0 protostar B335
Hsi-Wei Yen, Bo Zhao, Patrick Koch +6
We present our observational results of the 0.87 mm polarized dust emission in the Class 0 protostar B335 obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) at a…
