一旋转Kerr-Newman-Kasuya-De Sitter型行电恒星体的一些热力学性质

根据Kerr—Newman—Kasuya—De Sitter(KNKD)度规理论,我们讨论了一旋转荷电—荷磁恒星体的一些热力学性质,得到如下结论: 1.根据KNKD型度规理论,在一旋转荷电—荷磁恒星体的表面存在温度梯度。我们发现,温度从两极到赤道升高,且它们间存在温差。当恒星体半径在r=r_n的球面上坍缩到r=r_n=KQ～2/2R_g时,温度变成均匀的。如果它的半径坍缩到r>r_n的区域,则温度分布在r=常数的球面反转,即是说,两极的温度比赤道的高。很多物理现象将由这种温度梯度的结果而产生。 2.根据理论分析和计算,我们发现,宇宙性质对恒星的热力学性质有贡献。对类星体而言,这种效应更明显。通过观测类星体两极和赤道间的温差,能确定宇宙的空时结构,这对天体物理学是一有意义的结论。

Some Thermodynical Properties of a Rotating Kerr-Newman-Kasuya-De Sitter Type Stellar Object

We discuss some thermodynamical properties of a rotating charged magneton stellar object according the theory of Kerr-Newman-Kasuya-De Sitter (KNKD) metric. We obtain following conclusions: 1. According to the theory of KNKD type metric field, there exists a gradient of tempersture on the surface of a rotating, charged-magneton stellar object. We find that the temperature raises from poles to the equator and a temperature differences exist between then. When radiu of the object collapses to r=r_n=KQ~2/2R_g on the spherical surface of r=r_n, the temperature distribution becomes uniform. If its radiu collapses to tlle region of r>r_n, the temperature distribution is converse on a spherical surface of r=constant, that is to say the temperature on the poles being higher than that one on the equator. Many physical phe- nomena will occur as a result of this gradient of temperature. 2. According the theoretical calculation and analysis, we find the cosmological properties are contribution to the thermodynamical proper- ties of stellar. For the guasistellar, this effect is more evident. By observating the temperature differences of quasistellar between the poles and the equator, we can determine the spacetime structure of universe. This is a meaningful result for the astrophysics.
