JCMT BISTRO Observations: Magnetic Field Morphology of Bubbles Associated with NGC 6334
Mehrnoosh Tahani, Pierre Bastien, Ray S. Furuya +142
We study the HII regions associated with the NGC 6334 molecular cloud observed in the sub-millimeter and taken as part of the B-fields In STar-forming Region Observations (BISTRO)…
The JCMT BISTRO-2 Survey: Magnetic Fields of the Massive DR21 Filament
Tao-Chung Ching, Keping Qiu, Di Li +154
We present 850 m dust polarization observations of the massive DR21 filament from the B-fields In STar-forming Region Observations (BISTRO) survey, using the POL-2 polarimeter a…
Increasing mass-to-flux ratio from the dense core to the protostellar envelope around the Class 0 protostar HH 211
Hsi-Wei Yen, Patrick Koch, Chin-Fei Lee +7
To study transportation of magnetic flux from large to small scales in protostellar sources, we analyzed the Nobeyama 45-m N2H+ (1-0), JCMT 850 um polarization, and ALMA C18O (2-1)…
A Multi-Scale Picture of Magnetic Field and Gravity from Large-Scale Filamentary Envelope to Core-Accreting Dust Lanes in the High-Mass Star-Forming Region W51
Patrick M. Koch, Ya-Wen Tang, Paul T. P. Ho +6
We present 230 GHz continuum polarization observations with the Atacama Large Milimeter/Submillimeter Array (ALMA) at a resolution of 0$\farcs1$ (~au) in the high-mass st…
The JCMT BISTRO Survey: A Spiral Magnetic Field in a Hub-filament Structure, Monoceros R2
Jihye Hwang, Jongsoo Kim, Kate Pattle +157
We present and analyze observations of polarized dust emission at 850 m towards the central 1 pc 1 pc hub-filament structure of Monoceros R2 (Mon R2). The data are obta…
Kinematical Constraint on Eccentricity in the Protoplanetary Disk MWC 758 with ALMA
I-Hsuan Genevieve Kuo, Hsi-Wei Yen, Pin-Gao Gu +1
We analyzed the archival data of the and emission lines in the protoplanetary disk around MWC 758 obtained with the Atacama L…
A VLA View of the Flared, Asymmetric Disk Around the Class 0 Protostar L1527 IRS
Patrick D. Sheehan, John J. Tobin, Zhi-Yun Li +21
We present high resolution Karl G. Jansky Very Large Array (VLA) observations of the protostar L1527 IRS at 7 mm, 1.3 cm, and 2 cm wavelengths. We detect the edge-on dust disk at a…
Formation of the SDC13 Hub-Filament System: A Cloud-Cloud Collision Imprinted on The Multiscale Magnetic Field
Jia-Wei Wang, Patrick M. Koch, Ya-Wen Tang +6
Hub-filament systems (HFSs) are potential sites of protocluster and massive star formation, and play a key role in mass accumulation. We report JCMT POL-2 850 m polarization obs…
Effects of magnetic field orientations in dense cores on gas kinematics in protostellar envelopes
Aashish Gupta, Hsi-Wei Yen, Patrick Koch +16
Theoretically, misalignment between the magnetic field and rotational axis in a dense core is considered to be dynamically important in the star formation process, however, extent…
B-fields in Star-Forming Region Observations (BISTRO): Magnetic Fields in the Filamentary Structures of Serpens Main
Woojin Kwon, Kate Pattle, Sarah Sadavoy +149
We present 850 m polarimetric observations toward the Serpens Main molecular cloud obtained using the POL-2 polarimeter on the James Clerk Maxwell Telescope (JCMT) as part of th…
Observational constraints on disc sizes in protoplanetary discs in multiple systems in the Taurus region. II. Gas disc sizes
A. A. Rota, C. F. Manara, A. Miotello +13
The formation of multiple stellar systems is a natural by-product of the star-formation process, and its impact on the properties of protoplanetary discs and on the formation of pl…
