Filamentary Network and Magnetic Field Structures Revealed with BISTRO in the High-Mass Star-Forming Region NGC2264 : Global Properties and Local Magnetogravitational Configurations

Jia-Wei Wang, Patrick M. Koch, Seamus D. Clarke +154

We report 850 m continuum polarization observations toward the filamentary high-mass star-forming region NGC 2264, taken as part of the B-fields In STar forming Regions Observat…

Three-dimensional Simulations of Magnetospheric Accretion in a T Tauri Star: Accretion and Wind Structures Just Around Star

Shinsuke Takasao, Kengo Tomida, Kazunari Iwasaki +1

We perform three-dimensional magnetohydrodynamic simulations of magnetospheric accretion in a T Tauri star to study the accretion and wind structures in the close vicinity of the s…

Giant protostellar flares: accretion-driven accumulation and reconnection-driven ejection of magnetic flux in protostars

Shinsuke Takasao, Kengo Tomida, Kazunari Iwasaki +1

Protostellar flares are rapid magnetic energy release events associated with formation of hot plasma in protostars. In the previous models of protostellar flares, the interaction b…

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…

A Three-dimensional Simulation of a Magnetized Accretion Disk: Fast Funnel Accretion onto a Weakly Magnetized Star

Shinsuke Takasao, Kengo Tomida, Kazunari Iwasaki +1

We present the results of a global, three-dimensional magnetohydrodynamics simulation of an accretion disk with a rotating, weakly magnetized central star. The disk is threaded by…

The impact of the Hall effect during cloud core collapse:implications for circumstellar disk evolution

Yusuke Tsukamoto, Satoshi Okuzumi, Kazunari Iwasaki +2

We perform three-dimensional radiation non-ideal magnetohydrodynamics simulations and investigate the impact of the Hall effect on the angular momentum evolution in the collapsing…

Detection of submillimeter-wave [C I] emission in gaseous debris disks of 49 Ceti and Beta Pictoris

Aya E. Higuchi, Aki Sato, Takashi Tsukagoshi +8

We have detected [C I] 3P1-3P0 emissions in the gaseous debris disks of 49 Ceti and Beta Pictoris with the 10 m telescope of the Atacama Submillimeter Telescope Experiment, which i…

Bimodality of circumstellar disk evolution induced by Hall current

Y. Tsukamoto, K. Iwasaki, S. Okuzumi +2

The formation process of circumstellar disks is still controversial because of the interplay of complex physical processes that occurs during the gravitational collapse of prestell…

Effects of Ohmic and ambipolar diffusion on the formation and evolution of the first cores, protostars and circumstellar discs

Yusuke Tsukamoto, Kazunari Iwasaki, Satoshi Okuzumi +2

We investigate the formation and evolution of a first core, protostar, and circumstellar disc with a three-dimensional non-ideal (including both Ohmic and ambipolar diffusion) radi…

An explicit scheme for ohmic dissipation with smoothed particle magneto-hydrodynamics

Yusuke Tsukamoto, Kazunari Iwasaki, Shu-ichiro Inutsuka

In this paper, we present an explicit scheme for Ohmic dissipation with smoothed particle magneto-hydrodynamics (SPMHD). We propose a SPH discretization of Ohmic dissipation and so…
