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…
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…
Modeling of the ALMA HL Tau Polarization by Mixture of Grain Alignment and Self-scattering
Tomohiro Mori, Akimasa Kataoka
Dust polarization at (sub)millimeter wavelengths has been observed for many protoplanetary disks. Theoretically, multiple origins potentially contribute to the polarized emission b…
Solving grain size inconsistency between ALMA polarization and VLA continuum in the Ophiuchus IRS 48 protoplanetary disk
Satoshi Ohashi, Akimasa Kataoka, Nienke Van der Marel +6
The protoplanetary disk around Ophiuchus IRS 48 shows an azimuthally asymmetric dust distribution in (sub-)millimeter observations, which is interpreted as a vortex, where millimet…
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…
GW Ori: Interactions Between a Triple-star System and its Circumtriple Disk in Action
Jiaqing Bi, Nienke van der Marel, Ruobing Dong +17
GW Ori is a hierarchical triple system which has a rare circumtriple disk. We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 1.3 mm dust continuum and…
Super-resolution Imaging of the Protoplanetary Disk HD 142527 Using Sparse Modeling
Masayuki Yamaguchi, Kazunori Akiyama, Takashi Tsukagoshi +7
With an emphasis on improving the fidelity even in super-resolution regimes, new imaging techniques have been intensively developed over the last several years, which may provide s…
Scattering-induced intensity reduction: large mass content with small grains in the inner region of the TW Hya disk
Takahiro Ueda, Akimasa Kataoka, Takashi Tsukagoshi
Dust continuum observation is one of the best methods to constrain the properties of protoplanetary disks. Recent theoretical studies have suggested that the dust scattering at the…
