摘要:

在本文中,我们产生了一组解决方案,描述内部的$f(R,T)$理论的引力,承认共形运动的紧凑的明星。本文考虑由正常物质组成的流体分布的状态方程$p=ωρ$和$0<ω<1$,$ω$是状态方程参数。因此,我们探讨了几个方面的模型分析与图形表示检查的物理有效性,以及它在指定的观测约束连接到十几个紧凑的恒星候选人的可接受性。它表明,从所提出的模型,这些对象只是辐射致密星。

英文摘要:

In the present paper we generate a set of solutions describing the interior of a compact star under $f(R,T)$ theory of gravity which admits conformal motion. We consider the equation of state (EOS) $p=ωρ$ with $0<ω<1$ for the fluid distribution consisting normal matter, $ω$ being the EOS parameter. We therefore explore several aspects of the model analytically along with graphical representations to check the physical validity as well as acceptability of it within specified observational constraint in connection to a dozen of the compact star candidates. It is shown from the presented model that these objects are nothing but radiating compact stars.
