研究了中子星内部从两味夸克物质到三味夸克物质的相变过程。发现这个过程的时标短至10-7s,并且在相变中奇异夸克所参加的半轻子过程是中微子能量损失的主要过程。这样,1.4M⊙质量的中子星内部的非奇异-奇异夸克物质相变会有几个1051erg的能量以中微子形式发射出去,这将表现为一种中微子爆现象。The phase transition of two-flavor quark matter into strange matter in the interior of a neutron star is studied. It is shown that the timescale of the transition is less than 0.1μs and the s-quark semileptonic processes are of significance in neutrino emission during the transition. Owing to these processes, the transition in a whole neutron star will liberate several 1051 erg of energy as a neutrino burst.
