Abstract

We analyze the mass distributions of exoplanets of three groups: transit planets discovered by the Kepler telescope, those found in ground-based observational programs and with the CoRoT satellite, and planets discovered in the vicinity of red dwarfs (M class) with the radial-velocity method. The dependence of the mass distributions of the Kepler transit planets on the spectral class of the host stars (F, G, and K classes) are considered. Taking into account the most significant factors of observational selection, which are different for each of the groups of planets, it has been shown that the mass distributions of exoplanets can be described by a universal power law with the index close to −2: dN/dmm−2. For the planets orbiting the stars of different spectral classes (F, G, K, and M), no statistically significant difference has been found.

系外行星质量分布对宿主星光谱级的依赖

摘要

我们分析了三类系外行星的质量分布:由开普勒望远镜发现的过境行星,在地面观测计划中以及通过CoRoT卫星发现的过境行星,以及在红矮星(M级)附近发现的径向行星的行星。速度法。开普勒过渡行星的质量分布与宿主恒星的光谱类别(F,G和K类别)之间的相关性已得到考虑。考虑到观测选择的最重要因素(对于每个行星组而言都是不同的),已经表明,系外行星的质量分布可以用指数接近-2:d N的通用幂定律来描述。/ d mm −2。对于绕不同光谱类别(F,G,K和M)的恒星运行的行星,没有发现统计学上的显着差异。
