Hadron-quark mixed phase in hyperon stars
Toshiki Maruyama, Satoshi Chiba, Hans-Josef Schulze +1
We analyze the different possibilities for the hadron-quark phase transition occurring in beta-stable matter including hyperons in neutron stars. We use a Brueckner-Hartree-Fock ap…
Quark deconfinement transition in hyperonic matter
Toshiki Maruyama, Satoshi Chiba, Hans-Josef Schulze +1
We discuss the properties of the hadron-quark mixed phase in compact stars using a realistic equation of state of hyperonic matter and the MIT bag model. We find that the equation…
Nuclear pasta structures in neutron stars and the charge screening
Toshitaka Tatsumi, Toshiki Maruyama, Dmitri N. Voskresensky +2
Non-uniform structures of the nucleon matter are expected at subnuclear densities and above the nuclear density: they are called nuclear pastas and kaon pastas, respectively. We nu…
Neutron star properties with in-medium vector mesons
F. Weber, Gy. Wolf, T. Maruyama +1
We explore the impact of in-medium modification of the properties of vector mesons on the nuclear equation of state and neutron star properties. It is found that in-medium modifica…
Vlasov calculations of nuclear ground states
Aldo Bonasera, Toshiki Maruyama, Massimo Papa +1
We describe some properties of nuclear ground states using a microscopic Vlasov approach. We propose a new method to find the energy minimum of the system enforcing the fermionic n…
