Chinese and foreign scientists unravel the mystery of the evolution of two main types of exoplanets.

Recently, based on the large sample data observed by scientists from China and other countries using the national major scientific infrastructure Guo Shoujing Telescope, and combined with observation data from other satellites and telescopes abroad, it was discovered that "super-Earths" and "mini-Neptunes" follow different rules in terms of orbital eccentricity and period relationship. From a dynamical perspective, it was revealed that these two similar groups of planets have undergone different evolutionary paths. This achievement deepens the scientific community's understanding of the diversity of planetary systems, and also provides a clearer panorama for humans to fully understand the formation and evolution of exoplanets. The related results were published in the international academic journal "Science" on June 12th.
