Evolution of neutron stars with toroidal magnetic fields: Axisymmetric simulation in full general relativity
Kenta Kiuchi, Masaru Shibata, Shijun Yoshida
We study the stability of neutron stars with toroidal magnetic fields by magnetohydrodynamic simulation in full general relativity under assumption of axial symmetry. Nonrotating a…
Relativistic stars with purely toroidal magnetic fields
Kenta Kiuchi, Shijun Yoshida
We investigate the effects of the purely toroidal magnetic field on the equilibrium structures of the relativistic stars. The master equations for obtaining equilibrium solutions o…
The g-mode Excitation in the Proto Neutron Star by the Standing Accretion Shock Instability
Shijun Yoshida, Naofumi Ohnishi, Shoichi Yamada
The so-called "acoustic revival mechanism" of core-collapse supernova proposed recently by the Arizona group is an interesting new possibility. Aiming to understand the elementary…
R-mode oscillations of rapidly rotating barotropic stars in general relativity: Analysis by the relativistic Cowling approximation
Shijun Yoshida, Shin'ichirou Yoshida, Yoshiharu Eriguchi
We develop a numerical scheme for obtaining the -mode oscillations of rapidly rotating relativistic stars. In the present scheme, we neglect all metric perturbations and only ta…
Rapidly rotating superfluid neutron stars in Newtonian dynamics
Shijun Yoshida, Yoshiharu Eriguchi
We develop a formulation for constructing and examining rapidly rotating Newtonian neutron star models that contain two superfluids, taking account of the effect of the rotation ve…
Inertial modes of neutron stars with the superfluid core
Shijun Yoshida, Umin Lee
We investigate the modal properties of inertial modes of rotating neutron stars with the core filled with neutron and proton superfluids, taking account of entrainment effects betw…

Umin Lee, Shijun Yoshida
We investigate the modal properties of the -modes of rotating neutron stars with the core filled with neutron and proton superfluids, taking account of entrainment effects betwe…
Nonradial Oscillations of Neutron Stars with a Solid Crust -- Analysis in the Relativistic Cowling Approximation--
Shijun Yoshida, Umin Lee
Nonradial oscillations of relativistic neutron stars with a solid crust are computed in the relativistic Cowling approximation, in which all metric perturbations are ignored. For t…
The r-mode instability of neutron stars with the superfluid core
Umin Lee, Shijun Yoshida
This paper has been withdrawn by the authors, due to inappropriate discussions in Discussions.
R-mode oscillations of rapidly rotating Newtonian stars - A new numerical scheme and its application to the spin evolution of neutron stars
Shigeyuki Karino, Shin'ichirou Yoshida, Shijun Yoshida +1
We have developed a new numerical scheme to solve r-mode oscillations of {\it rapidly rotating polytropic stars} in Newtonian gravity. In this scheme, Euler perturbations of the de…
R-modes of neutron stars with a solid crust
Shijun Yoshida, Umin Lee
We investigate the properties of -mode oscillations of a slowly rotating neutron star with a solid crust, by taking account of the effects of the Coriolis force. For the modal a…
Rotational modes of non-isentropic stars and the gravitational radiation driven instability
Shijun Yoshida, Umin Lee
We investigate the properties of r-mode and inertial mode of slowly rotating, non-isentropic, Newtonian stars, by taking account of the effects of the Coriolis force and the centri…
A numerical study of the r-mode instability of rapidly rotating nascent neutron stars
Shin'ichirou Yoshida, Shigeyuki Karino, Shijun Yoshida +1
The first results of numerical analysis of classical r-modes of {\it rapidly} rotating compressible stellar models are reported. The full set of linear perturbation equations of ro…
Inertial modes of slowly rotating isentropic stars
Shijun Yoshida, Umin Lee
We investigate inertial mode oscillations of slowly and uniformly rotating, isentropic, Newtonian stars. Inertial mode oscillations are induced by the Coriolis force due to the sta…
