The optically thick rotating magnetic wind from a massive white dwarf merger product -- II. axisymmetric magnetohydrodynamic simulations
Yici Zhong, Kazumi Kashiyama, Shinsuke Takasao +2
We numerically construct a series of axisymmetric rotating magnetic wind solutions, aiming at exploring the observation properties of massive white dwarf (WD) merger remnants with…
Magnetic field transport in geometrically thick discs: multi-dimensional effects on the field strength and inclination angle
Ryoya Yamamoto, Shinsuke Takasao
We theoretically investigate the magnetic flux transport in geometrically thick accretion discs which may form around black holes. We utilize a two-dimensional (2D) kinematic mean-…
Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya
Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39
Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…
Stability and Ly emission of Cold Stream in the Circumgalactic Medium: impact of magnetic fields and thermal conduction
Nicolas Ledos, Shinsuke Takasao, Kentaro Nagamine
Cold streams of gas with temperatures around play a crucial role in the gas accretion on to high-redshift galaxies. The current resolution of cosmological simulatio…
Magnetohydrodynamic Model of Late Accretion onto a Protoplanetary Disk: Cloudlet Encounter Event
Masaki Unno, Tomoyuki Hanawa, Shinsuke Takasao
Recent observations suggest late accretion, which is generally nonaxisymmetric, onto protoplanetary disks. We investigated nonaxisymmetric late accretion considering the effects of…
Connecting theory of plasmoid-modulated reconnection to observations of solar flares
Andrew Hillier, Shinsuke Takasao
The short timescale of the solar flare reconnection process has long proved to be a puzzle. Recent studies suggest the importance of the formation of plasmoids in the reconnecting…
