| 英文摘要 | Neutrino emissivity (IURCA) from the direct URCA (dURCA) process and the URCA processes with K(-) and (K) over bar (0) condensations are considered simultaneously in neutron star matter. The neutrino emissivity due to the dURCA process plays a dominant role. However, antikaon condensations change the chemical potential of electrons, the effective masses of nucleons and the matrix elements of the reaction for the dURCA process. These changes make the neutrino emissivity for the dURCA process decrease. In this case, with antikaon condensations the total neutrino emissivity becomes lower. We believe that antikaon condensations are unfavorable for fast cooling of neutron stars. |
