Multiple choice

What is the name of the theory that explains the origin of gamma-ray bursts?

  1. The collapsar model

  2. The neutron star merger model

  3. The black hole merger model

  4. The magnetar model
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The collapsar model is the leading theory that explains the origin of gamma-ray bursts. The collapsar model proposes that gamma-ray bursts are produced by the collapse of a massive star. When a massive star collapses, it forms a black hole. The black hole then accretes matter from the surrounding star, which produces a powerful jet of particles. The jet of particles then interacts with the surrounding gas, which produces gamma rays.

Multiple choice

What is the name of the phenomenon that occurs when a gamma-ray burst is detected?

  1. A gamma-ray flash

  2. A gamma-ray burst

  3. A gamma-ray flare

  4. A gamma-ray storm
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A gamma-ray burst is a sudden and intense burst of gamma rays. Gamma-ray bursts are the most powerful explosions in the universe. They can release more energy in a few seconds than the Sun will release in its entire lifetime.

Multiple choice

What is the name of the phenomenon that occurs when a gamma-ray burst is followed by a long-lasting emission of gamma rays?

  1. A gamma-ray flash

  2. A gamma-ray burst

  3. A gamma-ray flare

  4. A gamma-ray storm
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A gamma-ray flare is a long-lasting emission of gamma rays that follows a gamma-ray burst. Gamma-ray flares can last for hours or even days. They are thought to be produced by the interaction of the jet of particles from the gamma-ray burst with the surrounding gas.
