S. K. Maurya, Y. K. Gupta, Saibal Ray

摘要:

本文提出了一种求解全球对称各向异性带电流体分布的算法。考虑一个新的源函数$ν(r)$,我们找到了一组物理上表现良好的、代表致密恒星模型的解。一项详细的研究特别表明,这些模型实际上与质量和半径方面的奇异恒星相对应。在这方面,我们研究了几个物理性质,如能量条件,稳定性,质量半径比,电荷含量,各向异性性质和表面红移通过图形和数学计算。这些研究的所有特征都与理论和观测中已有的证据非常一致。

英文摘要:

In the present paper we develop an algorithm for all spherically symmetric anisotropic charged fluid distribution. Considering a new source function $ν(r)$ we find out a set of solutions which is physically well behaved and represent compact stellar models. A detailed study specifically shows that the models actually correspond to strange stars in terms of their mass and radius. In this connection we investigate about several physical properties like energy conditions, stability, mass-radius ratio, electric charge content, anisotropic nature and surface redshift through graphical plots and mathematical calculations. All the features from these studies are in excellent agreement with the already available evidences in theory as well as observations.
