论文摘要
我们研究了Horndeski重力中偏心二元系统的轨道演变。该特定理论提供了一个测试台，可与数据进行深入的比较。我们通过计算辐射场的多极矩来计算二进制的能量损失率和角动量的变化速率。我们已经为偏心二进制物使用了适当的参数来计算其轨道偏心率和半高轴的衰减速率。然后，我们将此衰减速率与GR进行比较。
We study the orbital evolution of eccentric binary systems in Horndeski gravity. This particular theory provides a testbed to give insightful comparisons with data. We compute the rate of energy loss and the rate of change of angular momentum for the binaries by calculating the multipole moments of the radiation fields. We have used appropriate parameters for the eccentric binaries to compute the decay rates of its orbital eccentricity and semi-major axis. We then compare this decay rate with that of GR.
