On the Nucleon Effective Mass in Neutron Stars Cooling
Yuuki Sugiyama, Akira Dohi
The cooling of neutrons stars, which are composed of ultra-high-density nuclear matter, strongly depends on the equation of state because the dominant cooling sources are neutrinos…
Cooling of Hybrid Stars with a 2SC+ Phase
Tsuneo Noda, Akira Dohi, Nobutoshi Yasutake +3
Recently, Fujimoto, Fukushima & Weise (2019) have proposed a new colour-superconductive state, 2SC+ phase, which can be smoothly connected to the low-density baryon superflui…
Cooling of Isolated Neutron Stars with Hyperon-mixed Kaon-Condensation Matter
Bhavnesh Bhat, Akira Dohi, Takumi Muto +1
We investigate the thermal evolution of isolated neutron stars containing hyperon--mixed kaon--condensed matter, focusing on the role of proton superconductivity. The equation of s…
Gravitational waves from gaps of neutron stars
Akira Dohi, Asuka Ito, Shota Kisaka
The pulsar magnetosphere is a potential source of continuous gravitational waves due to the rapid charge-discharge process in short timescale, varying the electric-field energy den…
A low mass and radius neutron star candidate in XTE J1810-189?
Shoutao Ban, Helei Liu, Zhaosheng Li +7
Photosphere radius expansion (PRE) bursts provide a crucial tool for constraining the mass and radius of neutron stars. In this study, we analyze time-resolved spectroscopic data f…
High-Precision Mass Measurements of Proton-Rich Rh, Pd, Cd isotopes in the vicinity of 100Sn and Impact on X-Ray Burst and Supernova Nucleosynthesis
D. S. Hou, W. D. Xian, M. Rosenbusch +55
Using the ZeroDegree multi-reflection time-of-flight mass spectrograph of the CRISMASS project at RIKEN Radioactive Isotope Beam Factory, we performed high-precision mass measureme…
