意想不到的差距创造了两个高峰期的行星富含金属的太阳类单星
Unexpected gap creating two peaks in the periods of planets of metal-rich sunlike single stars
摘要：
在大约一年或更长的时间里，行星的堆积实际上是一个双峰峰，在一个主要的大行星群中，有一个宽而尖锐的间隙将堆积的峰值分开。由近40%的行星周期超过200天组成，在表面重力下没有恒星伴星的富金属恒星（如太阳）的行星周期显示出两个由人口稀少的区域分开的强烈峰值。蒙特卡罗测试表明，这种结构不太可能出现在随机分布中，与所有其他群体的对象进行比较表明，这种特征不太可能是由于观测效应。峰在间隙附近具有其最高密度。这两个峰值在单行星系统中最为明显，尽管在多行星系统中仍然存在差距。这些特征可能是质量不会比木星低太多的行星的特征，也许也不会比木星高太多。周期分布中存在明确的特征表明，行星形成可能比之前预期的更加均匀。
英文摘要：
The pileup of planets at periods of roughly one year and beyond is actually a bimodal peak with a wide, sharp gap splitting the peak of the pileup in a major population of large planets. Consisting of nearly 40\% of planets with periods past 200 days, the periods of the planets of metal-rich stars like the sun in surface gravity which do not have a stellar companion show two strong peaks separated by a sparsely populated region. Monte Carlo tests show that this structure is unlikely to occur in random distributions, and a comparison with objects from all the other populations show that this feature is unlikely to be due to observational effects. The peaks have their highest density next to the gap. These two peaks are most strongly seen in single-planet systems, though the gap persists in multiple planet systems. These features are likely characteristic of planets with masses not too much lower than Jupiter, and perhaps not too much higher. The presence of well-defined features in the period distribution show that planet formation may be much more uniform than previously expected.
