Neutrino Opacities in Neutron Stars with Kaon Condensates
Takumi Muto, Masatomi Yasuhira, Toshitaka Tatsumi +1
The neutrino mean free paths in hot neutron-star matter are obtained in the presence of kaon condensates. The kaon-induced neutrino absorption process, which is allowed only in the…
Nonequilibrium Weak Processes in Kaon Condensation II - Kinetics of condensation ---
Takumi Muto, Toshitaka Tatsumi, Naoki Iwamoto
The kinetics of negatively charged kaon condensation in the early stages of a newly born neutron star is considered. The thermal kaon process, in which kaons are thermally produced…
Nonequilibrium Weak Processes in Kaon Condensation I --- Reaction rate for the thermal kaon process ---
Takumi Muto, Toshitaka Tatsumi, Naoki Iwamoto
We investigate the thermal kaon process,in which kaons are thermally produced via nucleon-nucleon collisions.This process is relevant to nonequilibrium dynamics of kaon condensatio…
Axion Mass Limits from Cooling Neutron Stars
Hideyuki Umeda, Naoki Iwamoto, Sachiko Tsuruta +2
The thermal evolution of a neutron star is studied by including the energy loss due to axion emission. Two axion models and three types of neutron-star matter equation of state are…
