我们提出了一种方法来确认系统中的物体与多个过境系外行星候选人的行星性质。这种方法涉及傅立叶域分析的偏差，在渡越时间从一个恒定的周期，导致系统内的动态相互作用。结合观测到的凌日时间和动力学稳定性的质量限制，我们可以宣称发现了四个行星系统：开普勒-25、开普勒-26、开普勒-27和开普勒-28，其中包含八颗行星和一颗候选行星。
We present a method to confirm the planetary nature of objects in systems with multiple transiting exoplanet candidates. This method involves a Fourier-domain analysis of the deviations in the transit times from a constant period that result from dynamical interactions within the system. The combination of observed anticorrelations in the transit times and mass constraints from dynamical stability allow us to claim the discovery of four planetary systems, Kepler-25, Kepler-26, Kepler-27 and Kepler-28, containing eight planets and one additional planet candidate.
