Vaxcyte宣布股票与票据双重发行定价,合计募资约10亿美元

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。
