Scattering polarization of 3-m water-ice feature by large icy grains
Ryo Tazaki, Koji Murakawa, Takayuki Muto +2
Water ice has a strong spectral feature at a wavelength of approximately m, which plays a vital role in our understanding of the icy universe. In this study, we investigate th…
Distortion of Magnetic Fields in the Dense Core SL42 (CrA-E) in the Corona Australis Molecular Cloud Complex
Ryo Kandori, Motohide Tamura, Masao Saito +9
Detailed magnetic field structure of the dense core SL42 (CrA-E) in the Corona Australis molecular cloud complex was investigated based on near-infrared polarimetric observations o…
Distortion of Magnetic Fields in BHR 71
Ryo Kandori, Motohide Tamura, Masao Saito +9
The magnetic field structure of a star-forming Bok globule BHR 71 was determined based on near-infrared polarimetric observations of background stars. The magnetic field in BHR 71…
Dust Destruction by Charging: A Possible Origin of Grey Extinction Curves of Active Galactic Nuclei
Ryo Tazaki, Kohei Ichikawa, Mitsuru Kokubo
Observed extinction curves of active galactic nuclei (AGNs) are significantly different from those observed in the Milky Way. The observations require preferential removal of small…
Dust Destruction by Drift-Induced Sputtering in Active Galactic Nuclei
Ryo Tazaki, Kohei Ichikawa
Recent mid-infrared high spatial resolution observations have revealed that active galactic nuclei (AGNs) may host a polar dust region with the size of several pc, and such dust ma…
Distortion of Magnetic Fields in Barnard 335
Ryo Kandori, Masao Saito, Motohide Tamura +9
In this study, the detailed magnetic field structure of the dense protostellar core Barnard 335 (B335) was revealed based on near-infrared polarimetric observations of background s…
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…
Distortion of Magnetic Fields in a Starless Core V: Near-infrared and Submillimeter Polarization in FeSt 1-457
Ryo Kandori, Tetsuya Nagata, Ryo Tazaki +9
The relationship between submillimeter (submm) dust emission polarization and near-infrared (NIR) -band polarization produced by dust dichroic extinction was studied for the col…
Cooling timescale of dust tori in dying active galactic nuclei
Kohei Ichikawa, Ryo Tazaki
We estimate the dust torus cooling timescale once the active galactic nucleus (AGN) is quenched. In a clumpy torus system, once the incoming photons are suppressed, the cooling tim…
