S. K. Maurya, Ayan Banerjee, Phongpichit Channuie

摘要:

本文从理论上详细分析了流体各向异性分布下流体静力平衡致密物体的一类新的精确解。为了实现这一点,我们称之为度量函数之间的关系,即嵌入类一条件。研究是通过概括球形星的性质来进行的,重点是流体静力平衡方程,即,广义的托尔曼-奥本海默方程,在我们理解这些紧凑的对象。我们匹配的内部解决方案的外部Reissner-Nordstrom解决方案,并研究这种模型的一些物理特性,如能量条件,声速,质量半径关系的恒星。我们还表明,所获得的解决方案是兼容的紧凑对象Her X-1的观测数据。

英文摘要:

In this article we perform a detailed theoretical analysis for a class of new exact solutions with anisotropic fluid distribution of matter for compact objects in hydrostatic equilibrium. To achieve this we call the relation between the metric functions, namely, embedding class one condition. The investigation is carried out by generalising the properties of a spherical star with an emphasis on hydrostatic equilibrium equation, i.e., the generalised Tolman-Oppenheimer-Volkoff equation, in our understanding of these compact objects. We match the interior solution to an exterior Reissner-Nordstrom solution, and study some physical features of this models, such as the energy conditions, speeds of sound, and mass - radius relation of the star. We also show that obtained solution is compatible with observational data for compact object Her X-1.
