论文摘要
我们研究了某些 - 某些 - 摩肌缺陷模型的缩放和间距规则是否同时遵循尺度和间距规则。考虑了十个多星际系统中系外行星的质量和半轴轴。发现GJ 667C，HD 215152，HD 40307和Kepler-79系统目前靠近Angular-Momentum-Deficifit模型的配置。在气体贫困的情况下，GJ 3293，HD 141399和HD 34445系统过去曾经具有Angular-Momentum缺陷模型的配置，并且由于气态后效应而被散布。此外，无论在无气或贫困场景中，55 CNC，GJ 876和WASP-47系统都不会遵循Angular Momentum缺陷模型。因此，我们的结果揭示了这些多行星系统的重要形成历史。
We investigate whether certain extra-solar multi-planet systems simultaneously follow the scaling and spacing rules of the angular-momentum-deficit model. The masses and semi-major axes of exoplanets in ten multi-planet systems are considered. It is found that GJ 667C, HD 215152, HD 40307, and Kepler-79 systems are currently close to configurations of the angular-momentum-deficit model. In a gas-poor scenario, GJ 3293, HD 141399, and HD 34445 systems are those which had a configuration of the angular-momentum-deficit model in the past and get scattered away due to post gaseous effects. In addition, no matter in gas-free or gas-poor scenario, 55 Cnc, GJ 876, and WASP-47 systems do not follow the angular-momentum-deficit model. Therefore, our results reveal important formation histories of these multi-planet systems.
