论文摘要
众所周知，通过Tolman -Oppenheimer -Volkov（TOV）方程获得的一般相对论（GR）中的紧凑型物体的质量是一个明确的数量。但是，在替代性重力方面，情况并非如此。在$ f（t）$重力的特殊情况下，$ t $是标量扭转，一些作者认为这仍然是一个悬而未决的问题，因为不能保证在TOV GR中使用的相同方程式。在本文中，我们考虑了一个重要的问题，并比较了计算$ f（t）$重力中紧凑物体质量的不同方法。特别是，我们认为其中一个，即渐近质量，可能是计算该理论中质量的最合适方法。我们在本文介绍的所有模型中采用现实的状态方程。
The mass of compact objects in General Relativity (GR), which as is well known, is obtained via the Tolman - Oppenheimer - Volkov (TOV) equations, is a well defined quantity. However, in alternative gravity, this is not in general the case. In the particular case of $f(T)$ gravity, where $T$ is the scalar torsion, some authors consider that this is still an open question, since it is not guaranteed that the same equation used in TOV GR holds. In this paper we consider such an important issue and compare different ways to calculate the mass of compact objects in $f(T)$ gravity. In particular, we argue that one of them, the asymptotic mass, may be the most appropriate way to calculate mass in this theory. We adopt realistic equations of state in all the models presented in this article.
