苹果在 Safari 中测试代码,追踪谷歌推广 Chrome 的行为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。
