电磁场对大质量致密天体结构的影响

Effects of Electromagnetic Field on the Structure of Massive Compact Objects

M. Z. Bhatti, Z. Tariq

摘要:

本文包括一组恒星方程,管理的形成和演化的自引力,耗散球对称流体分布具有各向异性应力在电磁场的存在下。对黎曼张量进行正交分裂,得到五个标量函数,称为结构标量,并将其应用于恒星方程。结果表明,流体的一些基本性质,如能量密度的不均匀性,压力各向异性和热通量与所获得的标量是相互关联的。此外,它表明,所有的解决方案,爱因斯坦方程可以写在这五个标量保持鉴于静态的情况。

英文摘要:

This paper encompasses a set of stellar equations that administer the formation and evolution of self-gravitating, dissipative spherically symmetric fluid distributions having anisotropic stresses in the presence of electromagnetic field. The Riemann tensor is split orthogonally to procure five scalar functions named as structure scalars which are then utilized in the stellar equations. It is shown that some basic fluid properties such as energy density inhomogeneity, pressure anisotropy and heat flux are interlinked with the obtained scalars. Further, it is shown that all the solutions to Einstein equations can be written in terms of these five scalars keeping in view the static case.
