摘要

一项亚轨道实验表明，厘米大小的三电荷亚毫米级微粒群能够抵御碰撞速度高达 0.5 m s-1 左右的单个微粒的侵蚀。这些带电簇的稳定性使它们能够比不带电的簇长得更大，从而能够在原行星盘中形成行星。

Charged particles grow to stable planetesimal progenitors

A suborbital experiment indicates that centimetre-sized clusters of tribocharged submillimetre grains resist erosion by individual grains with collision speeds up to around 0.5 m s–1. The stability of these charged clusters allows them to grow larger than uncharged clusters, enabling the formation of planetesimals in protoplanetary disks.

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
