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.

本文包含一组恒星方程，该方程管理在电磁场存在下具有各向异性应力的自重，耗散球形对称流体分布的形成和演化。黎曼张量被正交分解，以获取五个被称为结构标量的标量函数，然后将其用于恒星方程。结果表明，一些基本的流体性质，例如能量密度不均匀性，压力各向异性和热通量与所获得的标量相互关联。此外，它表明，在考虑静态情况的情况下，可以用这五个标量来写出爱因斯坦方程的所有解。
