论文摘要
黑暗能量的概念可以是防止紧凑物体重力崩溃的候选者。根据Gravity的彩虹在紫外线完成一般相对论(通过提供新的时空描述)中的有用性,它可能是研究近相转变区域紧凑型物体行为的绝佳选择。在这项工作中,我们通过在重力彩虹中求解场方程来获得各向异性暗能量作为流体的改良的Tolman-Openheimer-volkof(TOV)方程。接下来,为了将结果与一般相对论进行比较,我们使用广义的Tolman-Matese-Whitman质量函数来确定黑暗能量星的能量密度,径向压力,横向压力,重力剖面和各向异性因子等物理量。我们评估了连接条件,并研究了重力彩虹中暗能量星薄壳的动态稳定性。我们还研究了该恒星内部区域的能量条件。我们表明,重力彩虹的系数可以显着影响这个非单一的紧凑型物体,并修改相变区域附近的模型。
The concept of dark energy can be a candidate for preventing the gravitational collapse of compact objects to singularities. According to the usefulness of gravity's rainbow in UV completion of general relativity (by providing a new description of spacetime), it can be an excellent option to study the behavior of compact objects near phase transition regions. In this work, we obtain a modified Tolman-Openheimer-Volkof (TOV) equation for anisotropic dark energy as a fluid by solving the field equations in gravity's rainbow. Next, to compare the results with general relativity, we use a generalized Tolman-Matese-Whitman mass function to determine the physical quantities such as energy density, radial pressure, transverse pressure, gravity profile, and anisotropy factor of the dark energy star. We evaluate the junction condition and investigate the dynamical stability of dark energy star thin shell in gravity's rainbow. We also study the energy conditions for the interior region of this star. We show that the coefficients of gravity's rainbow can significantly affect this non-singular compact object and modify the model near the phase transition region.
