Constraints on a vacuum energy from both SNIa and CMB temperature observations
Riou Nakamura, E. P. Berni Ann Thushari, Mikio Ikeda +1
We investigate the cosmic thermal evolution with a vacuum energy which decays into photon at the low-redshift. We assume that the vacuum energy is a function of the scale factor th…
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…
Cooling of Compact Stars with Color Superconducting Phase in Quark Hadron Mixed Phase
Tsuneo Noda, Masa-aki Hashimoto, Nobutoshi Yasutake +3
We present a new scenario for the cooling of compact stars considering the central source of Cassiopeia A (Cas A). The Cas A observation shows that the central source is a compact…
Explosive nucleosynthesis in the neutrino-driven aspherical supernova explosion of a non-rotating 15 star with solar metallicity
Shin-ichiro Fujimoto, Kei Kotake, Masa-aki Hashimoto +2
We investigate explosive nucleosynthesis in a non-rotating 15 star with solar metallicity that explodes by a neutrino-heating supernova (SN) mechanism aided by both standi…
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…
