Dependence of Hall Coefficient on Grain Size and Cosmic Ray Rate and Implication for Circumstellar Disk Formation
Shunta Koga, Yusuke Tsukamoto, Satoshi Okuzumi +1
The Hall effect plays a significant role in star formation because it induces rotation in the infalling envelope, which in turn affects the formation and evolution of the circumste…
JCMT BISTRO survey: Magnetic Fields within the Hub-Filament Structure in IC 5146
Jia-Wei Wang, Shih-Ping Lai, Chakali Eswaraiah +130
We present the 850 m polarization observations toward the IC5146 filamentary cloud taken using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and its associated polar…
Does misalignment between magnetic field and angular momentum enhance or suppress circumstellar disk formation?
Y. Tsukamoto, S. Okuzumi, K. Iwasaki +2
The effect of misalignment between the magnetic field $\magB$ and the angular momentum $\Jang$ of molecular cloud cores on the angular momentum evolution during the gravitational c…
Possible Counter Rotation between the Disk and Protostellar Envelope around the Class I Protostar IRAS 04169+2702
Shigehisa Takakuwa, Yusuke Tsukamoto, Kazuya Saigo +1
We present results from our SMA observations and data analyses of the SMA archival data of the Class I protostar IRAS 04169+2702. The high-resolution (~0.5") CO (3-2) image…
Magnetic fields towards Ophiuchus-B derived from SCUBA-2 polarization measurements
Archana Soam, Kate Pattle, Derek Ward-Thompson +121
We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its…
A First Look at BISTRO Observations of The Oph-A core
Jungmi Kwon, Yasuo Doi, Motohide Tamura +119
We present 850 m imaging polarimetry data of the Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2), as part of our…
