论文摘要
我们使用Tolman IV解决方案的各向异性扩展,在相对论一般理论下提出了一个紧凑的天体物理对象模型。源自该模型的各向异性函数在整个恒星内部保持良好状态。该模型满足了物理逼真的紧凑型星的几种必要条件。通过插入低质量X射线二进制(LMXB)候选4U 1608-52的估计参数值的估计参数值,我们对模型的物理生存能力进行了特殊验证。我们对该星的稳定性分析通过使用各种稳定性标准,提供令人满意的结果。与各向异性有关,我们计算紧凑型恒星模型的潮汐爱数(TLN),并将计算值与现有文献进行比较。
We present a model of compact astrophysical object under General Theory of Relativity using the anisotropic extension of Tolman IV solution. The anisotropy function, derived from the model, remains well behaved throughout the interior of the star. The model satisfies several necessary conditions for a physically realistic compact star. Physical viability of the model is verified specifically by plugging in the estimated parameter values of the Low Mass X-ray Binary (LMXB) candidate 4U 1608 - 52. Our stability analysis of this star, by using various criteria for stability, provide satisfactory results. In connection to anisotropy, we compute the Tidal Love Number (TLN) for the compact stellar model and compare the calculated values with existing literature.
