奇异状态方程的广义等温模型

Generalised isothermal models with strange equation of state

S. D. Maharaj, S. Thirukkanesh

摘要:

我们考虑的线性状态方程的物质分布,可能适用于奇异星的夸克物质。在我们的一般方法中,紧凑的相对论性物体允许在电磁场存在下的各向异性压力。发现了Einstein-Maxwell系统的新的精确解。一个特殊的情况下,被证明是定期在恒星中心。在各向同性极限下,我们得到了广义相对论等温宇宙。我们表明,质量对应的值以前得到的夸克星时,各向异性和收费。

英文摘要:

We consider the linear equation of state for matter distributions that may be applied to strange stars with quark matter. In our general approach the compact relativistic body allows for anisotropic pressures in the presence of the electromagnetic field. New exact solutions are found to the Einstein-Maxwell system. A particular case is shown to be regular at the stellar centre. In the isotropic limit we regain the general relativistic isothermal universe. We show that the mass corresponds to values obtained previously for quark stars when anisotropy and charge are present.
