论文摘要
在本文中，我们介绍了能量摩托明方重力（EMSG）的胶后近似值。该近似值用于研究EMSG背景下的重力通量。作为结果的应用，我们研究了EMSG对二元脉冲星轨道时期首次衍生物的效果。估计，通过使用此后杀伤性参数，EMSG理论的自由参数，$ f_0'$，估计为六个已知的二进制脉冲星。采取最准确的观察的二进制文件，事实证明$ -6 \ times 10^{ - 37} \ text {m} \，\ text {s}^2 \ text {kg}^{ - 1} <f_0'<+10^{ - 36} \ 36} \ text {m} {m} \，\，\，\，\ text {s}}这种界限与先例研究一致。
In this paper, we introduce the post-Minkowskian approximation of Energy-Momentum-Squared Gravity (EMSG). This approximation is used to study the gravitational energy flux in the context of EMSG. As an application of our results, we investigate the EMSG effect on the first time derivative of the orbital period of the binary pulsars. Utilizing this post-Keplerian parameter, the free parameter of the EMSG theory, $f_0'$, is estimated for six known binary pulsars. Taking the binaries that have the most accurate observations, it turns out that $-6\times 10^{-37}\text{m}\,\text{s}^2\text{kg}^{-1}<f_0'<+10^{-36}\text{m}\,\text{s}^2\text{kg}^{-1}$. This bound is in agreement with the precedent studies.
