D)neutron star mergers.
E)black hole mergers.

Question

Quizplus · Accepted Answer

Relatively long duration gamma-ray bursts are produced by hypernovae, which are explosions associated with the collapse of massive stars. The other options (novae, supernovae, neutron star mergers, and black hole mergers) do not typically produce gamma-ray bursts of this duration. Relatively long duration gamma-ray bursts are produced by hypernovae, which are incredibly energetic supernovae that result from the collapse of massive stars with masses over 30 times that of the Sun. These explosions launch jets of matter and radiation that can generate gamma-ray bursts.
