NICER Catches Milestone X-ray Burst

The video explains the observation of the brightest X-ray bursts from the binary system Sacks J 1808, located 11,000 light years away. It details the interaction between a pulsar and a brown dwarf, where hydrogen gas forms an accretion disk around the pulsar. Instability in the disk leads to X-ray brightening. The process involves hydrogen fusion and helium layer ignition, resulting in a type 1X burst. The video concludes with insights into the extreme physics of these eruptions, aiding in the understanding of accreting neutron stars.

How does the helium layer behave during the explosion of the pulsar?

What significance do the new observations have for scientists studying neutron stars?
