论文摘要
我们宣布，除了基于Eclipse Piming Piming Analysis的一个检测到的一个二进制系统外，还宣布了Kepler-451二进制系统周围的两个新的行星质量伴侣的检测。我们发现，一个最小质量为1.76 MJUP的内部行星和一个$ \ sim $ 1800 d轨道周期的外部行星，最小质量为1.61 MJUP，可以解释Eclipse Anting fit的残留物的周期性变化。我们将中部星球的轨道时期更新为406 d，并将其偏心率确定为0.33。新发现的外行星也位于偏心轨道上（0.29），而最内向的行星被认为具有圆形轨道。所有三个Jovian行星都具有相似的质量，我们的动力稳定性测试产生了系统稳定的。
We announce the detection of two new planetary-mass companions around Kepler-451 binary system in addition to the one detected previously based on eclipse timing variation analysis. We found that an inner planet with 43 d period with a minimum mass of 1.76 Mjup and an outer one with a $\sim$ 1800 d orbital period with a minimum mass of 1.61 Mjup can explain the periodic variations in the residuals of the one-planet fit of the eclipse timings. We updated the orbital period of the middle planet as 406 d, and determined its eccentricity as 0.33. The newly discovered outer planet is also on an eccentric orbit (0.29), while the innermost planet was assumed to have a circular orbit. All three Jovian planets have similar masses, and our dynamical stability test yields that the system is stable.
