摘要:

给出了多味极限下的非相互作用多强子费米子星状态方程与Kaluza,--,Klein紧致星自由度之间的对应关系.在这个框架中,许多味道都可以被解释为一个额外的空间维度,具有各种各样的,越来越多的质量强子态激发。研究了自由度的增加对状态方程的影响,并结合质量-半径关系$M(R)$。恒星的最大质量$M_{\mathrm{max}}$也被计算为最大激发态数$n$和紧化额外维度尺寸$R_{\mathrm{c}}$的函数。

英文摘要:

We present the correspondence between non-interacting multi-hadron fermion star equation of state in the many-flavor limit and the degrees of freedom of a Kaluza\,--\,Klein compact star. Many flavors can be interpreted in this framework as one extra compacti\-fied spatial dimension with various, more-and-more massive hadron state excitations. The effect of increasing the degrees of freedom was investigated on the equation of state and in connection with the mass-radius relation, $M(R)$. The maximum mass of the star, $M_{\mathrm{max}}$ were also calculated as a function of the maximum number of excited states, $n$ and the size of the compactified extra dimension, $R_{\mathrm{c}}$.
