10月5日跨区域人员流动量同比增1.7%2026年10月，天文学家在距离地球约300光年的位置发现一种特殊的双星互动：一颗低质量恒星正在缓慢吸收附近褐矮星的物质。该系统名为ZTF J0440+2325，两者距离很近，褐矮星约每87分钟绕行一圈，轨道整体可以容纳在太阳直径范围内，为研究小质量天体之间的物质交换提供了新实例。
研究最初来自巡天数据中反复出现的三角形亮度变化。后续望远镜观测表明，主星质量约为木星的85倍，伴星约为木星的25倍。模拟显示，伴星流出的物质可以直接撞向恒星表面，产生随轨道转动而进入或离开视线的明亮区域，从而解释特殊光变。按推算的转移速度，这一过程可能持续很长时间，而不是迅速吞没伴星。发现扩展了人们对恒星和亚恒星天体关系的认识，也说明长期保存的巡天异常信号值得重新分析。团队接下来希望寻找更多类似系统，检验这种演化方式有多普遍。
