Spotify有声书年内将覆盖超180个市场

2026年10月，天文学家重新分析哈勃空间望远镜历史光谱时，在白矮星HS 0209+0832系统发现异常化学线索，提出其附近可能存在由恒星晚期抛出物质形成的第二代行星。研究人员借助更新后的元素数据库，识别出以往难以解释的多条光谱特征，其中铌的信号受到特别关注。

白矮星是低质量恒星演化后留下的致密核心，形成前会向外释放大量物质。团队认为，这些富含特定元素的物质可能重新聚集，形成新的气态行星，从而解释观测到的异常丰度。该研究把保存多年的数据与改进的化学资料结合，说明旧观测仍可能提供新的发现。不过，目前证据主要来自光谱组成与演化模型，并不是直接拍摄到第二代行星，也不能把这一解释视为最终确认。后续需要更多观测检验物质来源和系统结构。如果推断得到支持，将说明行星形成可能并不只发生在恒星诞生时，还能出现在恒星生命晚期留下的环境中。
