求解$f(T)$引力中的Tolman-Oppenheimer-Escheroff方程:一种新的方法

Solving Tolman-Oppenheimer-Volkoff equations in $f(T)$ gravity: a novel approach

H. G. M. Fortes, J. C. N. de Araujo

摘要:

扭转模型在引力的另一种描述中脱颖而出。其中最简单的,Teleparallel理论,相当于广义相对论,有许多研究试图研究其扩展到更一般的扭转函数$T$。{我们的研究}的目的是考虑一族$f(T)$模型,并将其相应的Tolman-Oppenheimer-Schmidt方程应用于致密天体,如中子星。因此,通过数值分析,计算出中子星模型所允许的最大质量,这也将使我们能够评估哪些模型与观测相符。在本文件中,第一个系列,我们明确地显示了一组方程,必须解决,以及如何解决它,以模拟紧凑的恒星在$f(T)$重力,而不需要采取任何特定形式的度量函数或考虑任何微扰的方法,已经在一些作品中的文献。

英文摘要:

The torsion models have stood out among the proposals for an alternative description of gravity. The simplest of them, the Teleparallel theory, is equivalent to General Relativity and there are many studies that seek to study its extension to more general functions of the torsion $T$. The purpose of {our study } is to consider a family of $f(T)$ models and apply their corresponding Tolman-Oppenheimer-Volkof equations to compact objects such as neutron stars. Consequently, through a numerical analysis, calculate, among other things, the maximum mass allowed by the model for a neutron star, which would also allow us to evaluate which models are in accordance with observations. In the present paper, the first in the series, we show explicitly the set of equations that must be solved, and how to solve it, in order to model compact stars in $f(T)$ gravity without the need to adopt any particular form for the metric functions or consider any perturbative approach, as has been done in some works in the literature.
