  • 该团队利用上海65米射电望远镜(天马望远镜)首次在星际空间探测到异氰酸(HNCO)、重水(HDO)和甲醇同位素(13CH3OH)三种新的分子脉泽,并揭示它们正在示踪(大质量恒星形成过程中的)由引力不稳定性导致的星周盘碎裂产生的旋臂吸积流及间歇吸积现象 ...
    陈曦教授介绍说:“三种新脉泽(HDO、HNCO和13CH3OH)是由上海天马望远镜在2019年3月份对一颗正处于6.7 GHz甲醇脉泽闪耀阶段的大质量年轻恒星天体(G358.93-0.03) ...
    图2:天马望远镜监测获得的HDO,HNCO 和13CH3OH 三种脉泽成分的峰值流量随时间的变化。 这些脉泽成分辐射都展现了明显且快速的衰减现象,支持了大质量恒星形成的间歇吸积现象。
