论文摘要
我们提出了$ f（r，t）$重力框架中$ωRT$给出的一种重力 - 物质相互作用的形式，并检查了球形对称的紧凑型恒星中这种相互作用的效果。将重力耦合视为在Starobinsky重力背景下的扰动项，我们开发了一种平衡构型的扰动理论。为了插图，我们以夸克恒星为例，并探索它们的各种恒星特性。我们发现，重力耦合会导致稳定的最大质量增加，这与最近对二元脉冲星的观察有关。
We propose a form of gravity-matter interaction given by $ωRT$ in the framework of $f(R,T)$ gravity and examine the effect of such interaction in spherically symmetric compact stars. Treating the gravity-matter coupling as a perturbative term on the background of Starobinsky gravity, we develop a perturbation theory for equilibrium configurations. For illustration, we take the case of quark stars and explore their various stellar properties. We find that the gravity-matter coupling causes an increase in the stable maximal mass which is relevant for recent observations on binary pulsars.
