A necessary condition for supernova fallback invading newborn neutron-star magnetosphere
Yici Zhong, Kazumi Kashiyama, Toshikazu Shigeyama +1
We numerically investigate the dynamics of a supernova fallback accretion confronting with a relativistic wind from a newborn neutron star (NS). The time evolution of the accretion…
Transition region from turbulent to dead zone in protoplanetary disks: local shearing box simulations
Fulvia Pucci, Kengo Tomida, James Stone +3
The dynamical evolution of protoplanetary disks is of key interest for building a comprehensive theory of planet formation and to explain the observational properties of these obje…
Investigation of coronal properties of X-ray bright G-dwarf stars based on the solar surface magnetic field -- corona relation
Shinsuke Takasao, Ikuyuki Mitsuishi, Takuma Shimura +4
We investigated the coronal properties of G-dwarf stars including the Sun over a wide range of X-ray luminosity ( to …
Accretion Properties of PDS 70b with MUSE
Jun Hashimoto, Yuhiko Aoyama, Mihoko Konishi +4
We report a new evaluation of the accretion properties of PDS~70b obtained with VLT/MUSE. The main difference from previous studies in Haffert et al. (2019) and Aoyama & Ikoma (201…
Comparative Study of Data-driven Solar Coronal Field Models Using a Flux Emergence Simulation as a Ground-truth Data Set
Shin Toriumi, Shinsuke Takasao, Mark C. M. Cheung +4
For a better understanding of magnetic field in the solar corona and dynamic activities such as flares and coronal mass ejections, it is crucial to measure the time-evolving corona…
A new HLLD Riemann solver with Boris correction for reducing Alfvén speed
Tomoaki Matsumoto, Takahiro Miyoshi, Shinsuke Takasao
A new Riemann solver is presented for the ideal magnetohydrodynamics (MHD) equations with the so-called Boris correction. The Boris correction is applied to reduce wave speeds, avo…
