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…
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…
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…
Cosmic-ray ionization rate versus Dust fraction: Which plays a crucial role in the early evolution of the circumstellar disk?
Yudai Kobayashi, Daisuke Takaishi, Yusuke Tsukamoto
We study the formation and early evolution of young stellar objects (YSOs) using three-dimensional non-ideal magnetohydrodynamic (MHD) simulations to investigate the effect of cosm…
A new formation scenario of a counter-rotating circumstellar disk: spiral-arm accretion from a circumbinary disk in a triple protostar system
Daisuke Takaishi, Yusuke Tsukamoto, Yasushi Suto
We present the evolution of rotational directions of circumstellar disks in a triple protostar system simulated from a turbulent molecular cloud core with no magnetic field. We fin…
Misaligned Circumstellar Disks and Orbital Motion of the Young Binary XZ Tau
Takanori Ichikawa, Miyu Kido, Daisuke Takaishi +3
We report our analyses of the multi-epoch (2015-2017) ALMA archival data of the Class II binary system XZ Tau at Bands 3, 4 and 6. The millimeter dust continuum images show compact…
Star-disk alignment in the protoplanetary disks: SPH simulation of the collapse of turbulent molecular cloud cores
Daisuke Takaishi, Yusuke Tsukamoto, Yasushi Suto
We perform a series of three-dimensional smoothed particle hydrodynamics (SPH) simulations to study the evolution of the angle between the protostellar spin and the protoplanetary…
