Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the observable phenomena?Transient electromagnetic flares (UV, X-ray, optical), and sometimes relativistic jets (radio emission)
2. What happens when a star gets too close to a black hole?When a star gets too close to a supermassive black hole, the black hole’s gravity pulls harder on the side of the star nearer to it than on the far side. This difference, called a tidal force, can tear the star apart, turning it into a stream of debris.
3. Why do we see a bright flare when a star is destroyed?The torn‑up star’s material falls into the black hole, forming a hot accretion disk. The disk glows brightly in ultraviolet and X‑ray light, creating a flare that can last months or even years.

Differential Gravitational Force: The difference in gravitational pull across an object due to varying distances from a massive body.
Accretion Physics: The study of how matter falls onto and accumulates on massive celestial objects.
Relativistic Jets: Collimated streams of plasma ejected at speeds approaching the speed of light from compact objects.
