Distortion of Magnetic Fields in the Dense Core CB81 (L1774, Pipe 42) in the Pipe Nebula
Ryo Kandori, Motohide Tamura, Masao Saito +9
The detailed magnetic field structure of the starless dense core CB81 (L1774, Pipe 42) in the Pipe Nebula was determined based on near-infrared polarimetric observations of backgro…
Distortion of Magnetic Fields in a Starless Core VI: Application of Flux Freezing Model and Core Formation of FeSt 1-457
Ryo Kandori, Kohji Tomisaka, Masao Saito +9
Observational data for the hourglass-like magnetic field toward the starless dense core FeSt 1-457 were compared with a flux freezing magnetic field model (Myers et al. 2018). Fitt…
Distortion of Magnetic Fields in Barnard 68
Ryo Kandori, Motohide Tamura, Masao Saito +8
The magnetic field structure, kinematical stability, and evolutionary status of the starless dense core Barnard 68 (B68) are revealed based on the near-infrared polarimetric observ…
Clouds of Fluffy Aggregates: How They Form in Exoplanetary Atmospheres and Influence Transmission Spectra
Kazumasa Ohno, Satoshi Okuzumi, Ryo Tazaki
Transmission spectrum surveys have suggested the ubiquity of high-altitude clouds in exoplanetary atmospheres. Theoretical studies have investigated the formation processes of the…
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…
Nonsticky Ice at the Origin of the Uniformly Polarized Submillimeter Emission from the HL Tau Disk
Satoshi Okuzumi, Ryo Tazaki
Recent (sub)millimeter polarimetric observations toward the young star HL Tau have successfully detected polarization emission from its circumstellar disk. The polarization pattern…
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…
