摘要
本文根据ＳＵ（５）大统一模型耦合Ｅｉｎｓｔｅｉｎ－Ｙａｎｇ－Ｍｉｌｌｓ－Ｈｉｇｇｓ系统导出的旋转度规解，研究了带电荷、磁荷、ＳＵ（３）ｃ色荷的中子星表面温度的分布。结果表明：中子星在坍缩过程中可能出现表面温度的反转；同时发现了中子星的赤道与两极的温度差随着电荷与ＳＵ（３）ｃ色荷的增加而减小的规律。
Based on the rotating metric solution derived from the SU(5) Grand Unified Model (GUT) Coupled to Einstein-Yang-Mills-Higgs system, the temperature distributions on a surface of neutron star with electric, magnetic, SU(3)c colour charges have been studied in this paper. The conclusion shows that the temperature distribution will converse in the collapse of neutron star. We also found the fact that the difference of temperature between equator and poles of a neutron star will decrease n the increase of electric and SU(3)c colour charges.
