Spin-down of solar-mass protostars in magnetospheric accretion paradigm
Shinsuke Takasao, Masanobu Kunitomo, Takeru K. Suzuki +2
Stellar spin is one of the fundamental quantities that characterize a star itself and its planetary system. Nevertheless, stellar spin-down mechanisms in protostellar and pre-main-…
Spiral Magnetic Field and Their Role on Accretion Dynamics in the Circumnuclear Disk of Sagittarius A*: Insight from λ = 850 μm Polarization Imaging
Kazuki Sato, Hiroko Shinnaga, Ray S. Furuya +3
We showcase a study on the physical properties of the Circumnuclear Disk surrounding the Sgr A* of the Galactic Center, emphasizing the role of magnetic field (B field) with 0.47 p…
Effect of Magnetic diffusion in the Chromosphere on the Solar Wind
Masato Matsuoka, Takeru K. Suzuki, Takato Tokuno +1
We investigate non-ideal magnetohydrodynamical (MHD) effects in the chromosphere on the solar wind by performing MHD simulations for Alfvén-wave driven winds with explicitly includ…
A Novel Method to Constrain Tidal Quality Factor from A Non-synchronized Exoplanetary System
Takato Tokuno, Akihiko Fukui, Takeru K. Suzuki
We propose a novel method to constrain the tidal quality factor, , from an observed non-synchronized star-planet system consisting of a slowly rotating low-mass star and a clos…
Dynamics Near the Inner Dead-Zone Edges in a Proprotoplanetary Disk
Kazunari Iwasaki, Kengo Tomida, Shinsuke Takasao +2
We perform three-dimensional global non-ideal magnetohydrodynamic simulations of a protoplanetary disk containing the inner dead-zone edge. We take into account realistic diffusion…
