Cooling of Hybrid Stars with a 2SC+ Phase
Tsuneo Noda, Akira Dohi, Nobutoshi Yasutake +3
Recently, Fujimoto, Fukushima & Weise (2019) have proposed a new colour-superconductive state, 2SC+ phase, which can be smoothly connected to the low-density baryon superflui…
Magnetized Coulomb crystals in neutron star crusts
Cheng-Jun Xia, Toshiki Maruyama, Nobutoshi Yasutake +1
We investigate the properties of magnetized Coulomb crystals in neutron star crusts using a fully three-dimensional geometry with periodic boundary conditions. The electron density…
Multiquark clustering in neutron-star matter from color-spin molecular dynamics
Nobutoshi Yasutake, Yuta Mukobara, Aaron Park +2
We study the equation of state of neutron-star matter with color-spin molecular dynamics. The calculation includes the internal color and spin degrees of freedom and their time evo…
Chiral Symmetry in Dense Matter with Meson Condensation
Takumi Muto, Toshiki Maruyama, Toshitaka Tatsumi
Kaon condensation in hyperon-mixed matter [(+) phase], which may be realized in neutron stars, is discussed on the basis of chiral symmetry. With the use of the effective chi…
Elastic properties of nuclear pasta in neutron-star crusts
Cheng-Jun Xia, Toshiki Maruyama, Nobutoshi Yasutake +2
Based on the relativistic mean field (RMF) model with Thomas-Fermi approximation, we investigate the elastic properties of neutron star matter. The elastic constants are estimated…
