B-fields In STar-forming Region Observations (BISTRO): Dual-Wavelength Constraints on Size-Dependent Grain Alignment in Star-Forming Regions
Ray S. Furuya, David Berry, Pierre Bastien +65
We compared 450 and 850 m POL-2 observations from the James Clerk Maxwell Telescope at resolution. The median absolute difference in polarization angle between bands is…
Dust Growth in Evolving Filamentary Molecular Clouds: Signatures in Ionization, Resistivity, and Infrared Scattering
Hayato Uchimura, Yoshiaki Misugi, Daisuke Takaishi +4
Studies of dust growth in molecular clouds often prescribe the collapse history, leaving unclear how magnetic regulation of core formation shapes dust evolution and its observable…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
Early Planet Formation in Embedded Disks (eDisk). XVIII. Indication of a possible spiral structure in the dust-continuum emission of the protostellar disk around IRAS 16544-1604 in CB 68
Sanemichi Z. Takahashi, Shigehisa Takakuwa, Ryosuke Nakanishi +11
We performed numerical simulations along with radiative transfer calculations to reproduce an intriguing asymmetric shoulder feature in the dust-continuum emission of the protostel…
Nonthermal Velocity Dispersion in the Outer Disk of HL Tau
Jinshi Sai, Shigehisa Takakuwa, Hsi-Wei Yen +2
Turbulence in protoplanetary disks plays a crucial role in the evolution of disk structures and the planet formation process therein. However, the strength of the turbulence remain…
Ion-Neutral Drift Velocity as a Diagnostic of Dust Growth and Magnetic Field in Star-Forming Environments
Haruka Fukihara, Yusuke Tsukamoto, Hiroyuki Hirashita +2
Recent observations have revealed that the ion-neutral drift velocity in star-forming molecular clouds and dense cores is on the order of 100 m s^-1. Theoretical studies have shown…
Development of 1-D non-ideal MHD simulation code towards understanding Long-term Evolution of Protoplanetary Disk
Yudai Kobayashi, Daisuke Takaishi, Yusuke Tsukamoto +1
We developed a one-dimensional magnetohydrodynamic (MHD) simulation code to investigate the long-term evolution of protoplanetary disks with low computational cost. In this simulat…
"Ashfall" Induced by Molecular Outflow in Protostar Evolution. II. Analytical Study on the Maximum Size of Dust Grains Lifted by Outflows
Hayato Uchimura, Kudoh Takahiro, Yusuke Tsukamoto
In this paper, we study the dust dynamics in the molecular outflow using an analytical magnetohydrodynamical outflow model. Specifically, we investigate the maximum size of dust gr…
A statistical approach for interpreting polarized dust emission of the filamentary molecular clouds toward the estimate of 3D magnetic field structure
Haruka Fukihara, Daisuke Takaishi, Yoshiaki Misugi +2
In this study, we perform 3D magnetohydrodynamics (MHD) simulations of filamentary molecular clouds. We then generate synthetic observations based on the simulation results. Using…
Formation of unipolar outflow and in magnetized turbulent molecular cloud cores
Daisuke Takaishi, Yusuke Tsukamoto, Miyu Kido +4
Observed protostellar outflows exhibit a variety of asymmetrical features, including remarkable unipolar outflows and bending outflows. Revealing the formation and early evolution…
