天文学家对74颗恒星周围的Excomet带进行地图绘制,揭示了行星系统演变的洞察力。 Astronomers map exocomet belts around 74 stars, revealing insights into planetary system evolution.

天文学家利用ALMA和SMA望远镜绘制了约74颗近距离恒星的外星带地图。 Astronomers have mapped exocomet belts around 74 nearby stars using ALMA and SMA telescopes. 这些冰岩带至少有20%的时间被发现,其结构从窄环到宽盘不等,并含有作为外星碰撞残留物的石块。 These icy rocky belts, found at least 20% of the time, vary in structure from narrow rings to wide disks and contain pebbles that are remnants of exocomet collisions. 该研究 " 理由 " 也表明,无法探测的行星可能会影响这些带子,对行星系统的演变提供洞察。 The study, REASONS, also suggests undetectable planets may influence these belts, offering insights into planetary system evolution.
