Abstract:

Pion condensation in hot neutron matter is studied by solving the Hartree-Fock equation with effective interactions. Based on this, the characteristics of ν-burst from SN1987A; the time delay and the energy source for the last three ν-events detected by Kamiokande II, are discussed from a viewpoint of a pion-condensed neutron star.
