Capture the Lost Redback Spider in Globular Clusters

Do you know there're many invisible stars in the universe?

 

Scientists find shadowed pulsar binary system NGC 6397B with the longest orbit period among all eclipsing binary systems in globular clusters.

 

The eclipsing process of the pulsar binary star NGC 6397B is vividly likened to a female redback spider eating a male spider.

 

This discovery makes critical contributions to a deeper understanding of globular cluster evolution.

 

There may be a large number of faint and long-term radio-quiet binary pulsar systems in core-collapsed globular clusters.
