标题： Strange Quark Stars and Condensate Dark Stars in Bumblebee Gravity

摘要： 本文中，我们在最小标准模型扩展的框架内研究了由各向同性物质组成的相对论恒星的性质，在该框架中，与时空耦合的蜂鸟场（BF）诱导自发洛伦兹对称性破缺。 我们采用描述凝聚暗星或奇异夸克星的解析状态方程。 我们数值求解结构方程，并计算质量-半径关系。 详细检查了蜂鸟参数 $\mathbf{l}$ 的影响，并利用大质量脉冲星（PSR）J0740+6620和奇怪地轻的高能切伦科夫望远镜系统（HESS）J1731-347致密天体获得了上限。 显示英文摘要

摘要： In this paper, we investigate the properties of relativistic stars made of isotropic matter within the framework of the minimal Standard Model Extension, where a Bumblebee field (BF) coupled to spacetime induces spontaneous Lorentz symmetry breaking. We adopt analytic equations-of-state describing either condensate dark stars or strange quark stars. We solve the structure equations numerically, and we compute the mass-to-radius relationships. The influence of the Bumblebee parameter $\mathbf{l}$ is examined in detail, and an upper bound is obtained using the massive pulsar (PSR) J0740+6620 and the strangely light High Energy Stereoscopic System (HESS) J1731-347 compact object.
