| dc.description.abstract | In this work we have examined the formation of neutron stars (NSs) in the core of a supernova explosion during the death of massive stars, neutrino emission mechanisms in the interior of NSs under di erent assumptions on their internal structure, and the thermal history of NSs by determining neutrino luminosities and the temperature as a function of time. The emphasis is made on new results such as modi ed Urca process in a NS core with spherical nuclear structures since both momentum and energy are conserved in these reactions. Neutrino emission from NS cores containing exotic phases of matter (pion or kaon condensates,quarks) is also outlined. The e ects of neutrino emission on thermal histories of NSs , particularly cooling isolated stars, are examined | en_US |
