The detection of dust gap-ring structure in the outer region of the CR Cha protoplanetary disk
Seongjoong Kim, Sanemichi Takahashi, Hideko Nomura +13
We observe the dust continuum at 225 GHz and CO isotopologue (12CO, 13CO, and C18O) J=2-1 emission lines toward the CR Cha protoplanetary disk using the Atacama Large Millimeter/Su…
Radial variations in grain sizes and dust scale heights in the protoplanetary disk around HD 163296 revealed by ALMA polarization observation
Satoshi Ohashi, Akimasa Kataoka
The HD 163296 disk shows ring and gap substructures with ALMA observations. In addition, this is the only disk where the rings and gaps are spatially resolved in millimeter-wave po…
Investigating the gas-to-dust ratio in the protoplanetary disk of HD 142527
Kang-Lou Soon, Munetake Momose, Takayuki Muto +6
We present ALMA observations of the dust continuum and the and line emissions of the protoplanetary di…
An Observational Study for Grain Dynamics in the AS 209 Disk with Submillimeter Polarization
Tomohiro Mori, Akimasa Kataoka, Satoshi Ohashi +4
We present 870 m ALMA polarization observation toward the Class I\hspace{-.1em}I protoplanetary disk around AS 209, which has concentric, multiple gaps and rings. We successfull…
Unveiling Dust Aggregate Structure in Protoplanetary Disks by Millimeter-wave Scattering Polarization
Ryo Tazaki, Hidekazu Tanaka, Akimasa Kataoka +2
Dust coagulation in a protoplanetary disk is the first step of planetesimal formation. However, a pathway from dust aggregates to planetesimals remains unclear. Both numerical simu…
One Solution to the Mass Budget Problem for Planet Formation: Optically Thick Disks with Dust Scattering
Zhaohuan Zhu, Shangjia Zhang, Yan-Fei Jiang +10
ALMA surveys have suggested that the dust in Class II disks may not be enough to explain the averaged solid mass in exoplanets, under the assumption that the mm disk continuum emis…
Dust Polarization in Four Protoplanetary Disks at 3 mm: Further Evidence of Multiple Origins
Rachel E. Harrison, Leslie W. Looney, Ian W. Stephens +7
We present polarimetric observations of four Class II protoplanetary disks (DG Tau, Haro 6-13, RY Tau, and MWC 480) taken with the Atacama Large Millimeter/submillimeter Array (ALM…
The JCMT BISTRO Survey: The Magnetic Field of the Barnard 1 Star-Forming Region
Simon Coudé, Pierre Bastien, Martin Houde +118
We present the POL-2 850 m linear polarization map of the Barnard 1 clump in the Perseus molecular cloud complex from the B-fields In STar-forming Region Observations (BISTRO) s…
Polarization in Disks
Ian Stephens, Zhi-Yun Li, Haifeng Yang +24
Polarized dust emission outside of disks reveal the magnetic field morphology of molecular clouds. Within disks, however, polarized dust emission can arise from very different mech…
Millimeter-wave polarization due to grain alignment by the gas flow in protoplanetary disks
Akimasa Kataoka, Satoshi Okuzumi, Ryo Tazaki
Dust grains emit intrinsic polarized emission if they are elongated and aligned in the same direction. The direction of the grain alignment is determined by external forces, such a…
Effect of dust size and structure on scattered light images of protoplanetary discs
Ryo Tazaki, Hidekazu Tanaka, Takayuki Muto +2
We study scattered light properties of protoplanetary discs at near-infrared wavelengths for various dust size and structure by performing radiative transfer simulations. We show t…
Tensile Strength of Porous Dust Aggregates
Misako Tatsuuma, Akimasa Kataoka, Hidekazu Tanaka
Comets are thought to have information about the formation process of our solar system. Recently, detailed information about comet 67P/Churyumov-Gerasimenko has been found by a spa…
The JCMT BISTRO Survey: The Magnetic Field In The Starless Core Ophiuchus C
Junhao Liu, Keping Qiu, David Berry +128
We report 850~m dust polarization observations of a low-mass (12 ) starless core in the Ophiuchus cloud, Ophiuchus C, made with the POL-2 instrument on the…
