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…
Theoretical and Experimental Constraints for the Equation of State of Dense and Hot Matter
Rajesh Kumar, Veronica Dexheimer, Johannes Jahan +57
This review aims at providing an extensive discussion of modern constraints relevant for dense and hot strongly interacting matter. It includes theoretical first-principle results…
Neutron star mass formula with nuclear saturation parameters for asymmetric nuclear matter
Hajime Sotani, Shinsuke Ota
Low-mass neutron stars are directly associated with the nuclear saturation parameters because their central density is definitely low. We have already found a suitable combination…
Effects of finite sizes of atomic nuclei on shear modulus and torsional oscillations in neutron stars
Hajime Sotani, Hajime Togashi, Masatoshi Takano
The shear modulus of neutron star matter is one of the important properties for determining torsional oscillations in neutron stars. We take into account the effects of finite size…
Neutron star mass formula with nuclear saturation parameters
Hajime Sotani, Hajime Togashi
We derive the empirical formulas for the neutron star mass and gravitational redshift as a function of the central density and specific combination of the nuclear saturation parame…
Neutron-star radii based on realistic nuclear interactions
Y. Yamamoto, H. Togashi, T. Tamagawa +3
The existence of neutron stars with requires the strong stiffness of the equation of state (EoS) of neutron-star matter. We introduce a multi-pomeron exchange potential…
Nuclear equation of state for core-collapse supernova simulations with realistic nuclear forces
H. Togashi, K. Nakazato, Y. Takehara +3
A new table of the nuclear equation of state (EOS) based on realistic nuclear potentials is constructed for core-collapse supernova numerical simulations. Adopting the EOS of unifo…

The equation of state (EOS) for hot asymmetric nuclear matter which is constructed with the variational method starting from the Argonne v18 and Urbana IX nuclear forces is applied…
Variational study for the equation of state of asymmetric nuclear matter at finite temperatures
H. Togashi, M. Takano
An equation of state (EOS) for uniform asymmetric nuclear matter (ANM) is constructed at zero and finite temperatures by the variational method starting from the nuclear Hamiltonia…
