A Lagrangian construction of rotating stars
Misa Ogata, Hirotada Okawa, Kotaro Fujisawa +3
We present a new formulation for numerically obtaining axisymmetric equilibrium structures of rotating stars in two spatial dimensions. With a view to apply it to the secular evolu…
Elastic properties of nuclear pasta in a fully three-dimensional geometry
Cheng-Jun Xia, Toshiki Maruyama, Nobutoshi Yasutake +2
Realistic estimations on the elastic properties of neutron star matter are carried out with a large strain () in the framework of relativistic-mean-field…
Nuclear pasta structures at high temperatures
Cheng-Jun Xia, Toshiki Maruyama, Nobutoshi Yasutake +1
We investigate nuclear pasta structures at high temperatures in the framework of relativistic mean field model with Thomas-Fermi approximation. Typical pasta structures (droplet, r…
A novel formulation for the evolution of relativistic rotating stars
Hirotada Okawa, Kotaro Fujisawa, Nobutoshi Yasutake +3
We present a new formulation to construct numerically equilibrium configurations of rotating stars in general relativity. Having in mind the application to their quasi static evolu…
Singularity-Avoiding Multi-Dimensional Root-Finder
Hirotada Okawa, Kotaro Fujisawa, Yu Yamamoto +3
We proposed in this paper a new method, which we named the W4 method, to solve nonlinear equation systems. It may be regarded as an extension of the Newton-Raphson~(NR) method to b…
