论文摘要
本文的目的是使用扩展引力理论（也称为$ f（\ MATHCAL {r}，\ MATHCAL {G}，\ MATHCAL {T}）$ GRAVITY。另外，该理论也称为$ f（\ Mathcal {r}，\ Mathcal {t}，\ Mathcal {g}）$ gravity。符号$ \ MATHCAL {r}，\ MATHCAL {G} $和$ \ MATHCAL {T} $分别表示Ricci标量，高斯 - 骨网不变和能量巨头张量的痕迹。我们在这种新的重力理论的框架中提出了几种合理的模型，然后使用这些模型探索相对论性质紧凑对象的几种物理特性。这项研究还考虑了三个著名的紧凑型恒星：Vela X-1（CS1）； SAXJ1808.4-3658（CS2）;和4U1820-30（CS3）。此外，使用建议的模型，各向异性应力，能量密度，各种能量条件（EC），平衡状态，内部稳定性，质量变化，紧凑，各向异性，电荷和电场强度的状态进行了经过考虑的紧凑型星的分析。为此分析提供了上述数量的不同图。结论性地，EC得到满足，紧凑型恒星具有明显的致密芯。
The purpose of this paper is to study charged compact stars using extended gravitational theory, also known as $f(\mathcal{R}, \mathcal{G}, \mathcal{T})$ gravity. Alternatively, this theory is also called $f(\mathcal{R}, \mathcal{T}, \mathcal{G})$ gravity. The symbols $\mathcal{R}, \mathcal{G}$, and $\mathcal{T}$ denote the Ricci Scalar, the Gauss-Bonnet invariant, and the trace of the energy-momentum tensor, respectively. We suggested several plausible models in the framework of this new gravity theory, and then used these models to explore several physical properties of compact objects of relativistic nature. This research also takes into account three famous compact stars: Vela X-1 (CS1); SAXJ1808.4-3658 (CS2); and 4U1820-30 (CS3). Moreover, using the suggested models, the physical nature of anisotropic stress, energy density, various energy conditions (ECs), the state of equilibrium, interior stability, mass variations, compactness, anisotropy, electric charge, and electric field intensity are analysed for considered compact stars. Different plots of the above-mentioned quantities are presented for this analysis. Conclusively, the ECs are satisfied, and the compact stars have a significant dense core.
