论文摘要
我们研究了洛伦兹（Lorentz）侵略理论的非旋转和各向同性奇怪的夸克恒星，尤其是在Ho树重力和Einstein-æther理论中。对于Quark Matter，我们同时采用线性和非线性状态方程，分别对应于MIT袋模型和颜色风味锁定状态。描述静水平衡的新结构方程将爱因斯坦一般相对论的通常的Tolman-Oppenheimer-Volkoff（TOV）方程式推广。无量纲参数$ν$测量与标准TOV方程的偏差，这些方程在限制$ν\ rightarrow 0 $中恢复。我们计算恒星的质量，半径和紧凑性，并以图形方式显示了参数$ν$对质量到拉迪乌斯概况的影响对描述夸克物质的不同状态方程的影响。还考虑了能源条件和稳定标准，并且发现它们都可以满足。
We study non-rotating and isotropic strange quark stars in Lorentz-violating theories of gravity, and in particular in Hořava gravity and Einstein-æther theory. For quark matter we adopt both linear and non-linear equations of state, corresponding to the MIT bag model and colour flavour locked state, respectively. The new structure equations describing hydrostatic equilibrium generalize the usual Tolman-Oppenheimer-Volkoff (TOV) equations of Einstein's general relativity. A dimensionless parameter $ν$ measures the deviation from the standard TOV equations, which are recovered in the limit $ν\rightarrow 0$. We compute the mass, the radius as well as the compactness of the stars, and we show graphically the impact of the parameter $ν$ on the mass-to-radius profiles for different equations of state describing quark matter. The energy conditions and stability criteria are also considered, and they are all found to be fulfilled.
