论文摘要
我们分析已知的多行星系统（$ n \ geq 3 $）在平均值比率平面上的分布，并将其与由两行型平均动作共振（2p-mmr）和纯3型型号的共振产生的共振网络（纯3P-MMR）（纯3P-MMR）进行比较。我们发现，观察到的紧凑型低质量系统的分布与共振结构之间存在统计学意义的相关性的有趣证据，表明可能是因果关系。尽管Kepler-60，Kepler-80和Trappist-1等共振链是强大的贡献者，但大多数相关性似乎是由未识别为共振链的系统引起的。最后，我们在原始光盘和/或偏心型阻尼过程的最后阶段通过行星迁移讨论了它们可能的起源。
We analyze the distribution of known multi-planet systems ($N \geq 3$) in the plane of mean-motion ratios, and compare it with the resonance web generated by two-planet mean-motion resonances (2P-MMR) and pure 3-planet commensurabilities (pure 3P-MMR). We find intriguing evidence of a statistically significant correlation between the observed distribution of compact low-mass systems and the resonance structure, indicating a possible causal relation. While resonance chains such as Kepler-60, Kepler-80 and TRAPPIST-1 are strong contributors, most of the correlation appears to be caused by systems not identified as resonance chains. Finally, we discuss their possible origin through planetary migration during the last stages of the primordial disc and/or an eccentricity damping process.
