论文摘要
夸克恒星是在超高密度和温度下研究基本物理学的陆地实验室。在这项工作中，我们研究了rastall重力中夸克恒星（QSS）的内部结构和物理特性。 rastall重力被认为是一种非保守的重力理论，这是高能量密度的有效重力理论，例如与早期宇宙和密集，紧凑的物体有关。我们在包含各向异性压力的情况下得出了QSS的静水平衡结构。更具体地说，我们发现MIT袋模型的QS Mass-Radius关系。我们将重点放在模型上，具体取决于Rastall Free参数$η$，并检查与一般相对性（GR）对应物的偏差。
Quark stars are terrestrial laboratories to study fundamental physics at ultrahigh densities and temperatures. In this work, we investigate the internal structure and the physical properties of quark stars (QSs) in the Rastall gravity. Rastall gravity is considered a non-conservative theory of gravity, which is an effective gravity theory at high energy density, e.g., relevant to the early universe and dense, compact objects. We derive the hydrostatic equilibrium structure for QSs with the inclusion of anisotropic pressure. More specifically, we find the QS mass-radius relations for the MIT bag model. We focus on the model depending on the Rastall free parameter $η$ and examine the deviations from the General Relativity (GR) counterparts.
