摘要
用手征强子模型研究在中微子束缚情况下对致密物质状态及其对前中子星结构的影响 .结果表明中微子束缚效应提高了致密物质中质子的含量 ,使致密物质的状态方程变软 。
A chiral hadronic model is extended to investigate the influences of trapped neutrinos on the equation of state of dense matter and structure of protoneutron stars. Our results show that trapped neutrinos lead to the increase of proton fraction and make the equation of state of dense matter soft. Furthermore, maximum masses and radii of protoneutron stars decrease when neutrinos are trapped.
