Influence of effective mass of the relativistic mean field theory on core collapse supernovae and compact objects
Kohsuke Sumiyoshi, Hajime Togashi, Shun Furusawa +4
We study the influence of the effective mass in the relativistic mean field (RMF) theory on the properties of the central core of collapse-driven supernovae and the formation of co…

The -mode frequencies in cold neutron stars and nuclear saturation parameters
Hajime Sotani, Hajime Togashi
Oscillation frequencies excited in neutron stars are crucial for extracting their interior properties. In addition to the fundamental and pressure modes, the gravity (-) modes c…

Role of symmetry energy at subnuclear densities in protoneutron star crusts
Ken'ichiro Nakazato, Hajime Togashi, Kohsuke Sumiyoshi +1
The impact of matter properties at subnuclear densities on the evolution of protoneutron stars is investigated. Several models of nuclear equation of state (EOS) are constructed wi…
