Effects of Nuclear Equation of State on Type-I X-ray Bursts: Interpretation of the X-ray Bursts from GS 1826-24
A. Dohi, N. Nishimura, M. Hashimoto +3
Type I X-ray bursts are thermonuclear explosions on the neutron star (NS) surface caused by mass accretion from a companion star. Observations of X-ray bursts provide valuable info…
Quiescent luminosities of accreting neutron stars with different equation of states
Helei Liu, Akira Dohi, Masa-aki Hashimoto +3
We model the quiescent luminosity of accreting neutron stars with several equation of states (EOSs), including the effect of pion condensation and superfluidity. As a consequence o…
An approach to constrain models of accreting neutron stars with the use of an equation of state
Akira Dohi, Masa-aki Hashimoto, Rio Yamada +2
We investigate X-ray bursts during the thermal evolution of an accreting neutron star which corresponds to the X-ray burster GS\ 1826-24. Physical quantities of the neutron star ar…
Possibility of rapid neutron star cooling with the realistic equation of state
Akira Dohi, Ken'ichiro Nakazato, Masa-aki Hashimoto +2
Whether fast cooling processes occur or not is crucial for the thermal evolution of neutron stars. In particular, the threshold of the direct Urca process, which is one of the fast…
Quiescent Light Curve of Accreting Neutron Star MAXI J0556-332
Helei Liu, Yasuhide Matsuo, Masa-aki Hashimoto +2
MAXI J0556-332 is the hottest transient accreting neutron star at the beginning of its quiescence. A theoretical model with crustal heating indicates that an additional shallow hea…
Thermal structures of accreting neutron stars with neutrino losses due to strong pion condensations
Yasuhide Matsuo, Masa-aki Hashimoto, Koutarou Hayashida +3
Quiescent X-ray luminosities are presented in low mass X-ray binaries with use of evolutionary calculations. The calculated luminosities are compared with observed ones in terms of…
Effects of a New Triple-α Reaction on the S-process in Massive Stars
Yukihiro Kikuchi, Masaomi Ono, Yasuhide Matsuo +2
Effects of a new triple-α reaction rate on the s-process during the evolution of a massive star of 25 M\odot are investigated for the first time. Although the s-process in massive…
Effects of a New Triple-alpha Reaction on X-ray Bursts of a Helium Accreting Neutron Star
Y. Matsuo, H. Tsujimoto, T. Noda +4
The effects of a new triple- reaction rate (OKK rate) on the helium flash of a helium accreting neutron star in a binary system have been investigated. Since the ignition points…
