过去十年收集的关于系外行星性质的统计结果为行星形成模型提供了强有力的约束。它们现在被证明对于最近通过改进径向速度揭示的新类别的非常低质量的固体行星特别重要，主要由HARPS光谱仪获得。在这里，我们审查这个新发现的人口的新兴属性，根据国家的最先进的行星形成模型的结果。我们还讨论了径向速度方法的局限性和相关的乐观的前景，为未来的太阳型恒星的宜居带中的类地行星的探测，径向速度单独或补充空间测光。
The statistical results gathered on exoplanet properties over the past decade provide strong constraints for planet-formation models. They now prove to be especially important for the new category of very low-mass solid planets recently revealed by improved radial velocities, obtained mainly with the HARPS spectrograph. We review here the emerging properties of this newly discovered population, in the light of results from state-of-the-art planet-formation models. We also discuss the limitations of the radial-velocity method and the associated optimistic perspectives for the future detection of Earth-like planets in the Habitable Zone of solar-type stars, with radial velocities alone or in complement to space photometry.
