| Research Abstract |
In the study of cooling curves of compact stars, we have considered the cases of the formation of quark stars and/or strange stars. Then we investigate the effects of particular emission processes of neutrinos on the supernova explosions. Furthermore, we applied our formulations to a compact star in the supernova remnant Cas A in these 10 years. As a consequence, we can explain the cooling curve by including the neutrino emission accompanied to the phase transition to super fluid state.
