Equation of state for neutron star matter with NJL model and Dirac-Brueckner-Hartree-Fock approximation
Takahide Kambe, Tetsuya Katayama, Koichi Saito
As the interior density of a neutron star can become very high, it has been expected and discussed that quark matter may exist inside it. To describe the transition from hadron to…
Hyperons in neutron stars
Tetsuya Katayama, Koichi Saito
Using the Dirac-Brueckner-Hartree-Fock approach, the properties of neutron-star matter including hyperons are investigated. In the calculation, we consider both time and space comp…
Neutron stars with Hyperons in Dirac-Brueckner-Hartree-Fock approach
Tetsuya Katayama, Koichi Saito
Using the Dirac-Brueckner-Hartree-Fock (DBHF) approach including the hyperon degrees of freedom, we investigate the properties of neutron-star matter. To handle the hyperons in mat…
Properties of dense, asymmetric nuclear matter in Dirac-Brueckner-Hartree-Fock approach
Tetsuya Katayama, Koichi Saito
Within the Dirac-Brueckner-Hartree-Fock approach, using the Bonn potentials, we investigate the properties of dense, asymmetric nuclear matter and apply it to neutron stars. In the…
EoS for massive neutron stars
Tetsuya Katayama, Tsuyoshi Miyatsu, Koichi Saito
Using relativistic Hartree-Fock approximation, we investigate the properties of the neutron-star matter in detail. In the present calculation, we consider not only the tensor coupl…
Effects of Fock term, tensor coupling and baryon structure variation on a neutron star
Tsuyoshi Miyatsu, Tetsuya Katayama, Koichi Saito
The equation of state for neutron matter is calculated within relativistic Hartree-Fock approximation. The tensor couplings of vector mesons to baryons are included, and the change…
