意大利8月失业率攀升至6.2%,超出市场预期

2026年10月,天文学家利用韦布空间望远镜和斯皮策望远镜的历史数据,研究年轻恒星周围异常富含温暖尘埃的碎屑盘,希望寻找岩质天体剧烈碰撞留下的线索。团队汇集21个系统进行分析,把尘埃的矿物组成、颗粒大小和亮度变化联系起来,比较这些环境的形成过程。

研究发现,这类极端碎屑盘通常含有较小颗粒、大量温暖尘埃,并呈现不规则的亮度变化。通过中红外光谱,团队进一步将样本分为富含二氧化硅和相对缺少二氧化硅两类,用于判断产生碎屑的碰撞可能具有怎样的条件。类似研究有助于理解年轻行星系统中物质如何重新分配,也为讨论早期地球与月球形成所涉及的撞击提供参照。不过,望远镜观测到的是尘埃和辐射留下的结果,并非直接拍摄到行星相撞。不同矿物特征需要结合模型解释,团队也将继续通过更多样本检验这些特殊碎屑盘为何较少被发现。
