海尔-波普彗星的碎片

The Fragment of Comet Hale-Bopp

1997年 3月 4日、3月 17日使用南京紫金山天文合 2 0 0mm折射望远镜对海尔 -波普彗星作近核观测 ,观测到该彗星的彗核呈现小规模分裂 ,分离核碎块上拥有自己的喷流。分离核投影在天空切平面上的最大离核距离约为 2 .19× 10 4 km ,小碎块上喷流的投影长度为 5 .0 4× 10 3 km ,并对照片作了像增强处理。

This paper simply describes the small scale splitting of the nucleus of Comet Hale-Bopp which was observed on March 4th, 17th, 1997 by use of 200mm refractor at Purple Mountain Observatory. It is also shown that the separated small fragment of the nucleus has its own jet with a projective length of 5.04×10 3km, while the maximum projective distance between the two separated nuclei is about 2.19×10 4km. The data are processed by use of image enhancement technique.
