collapsarhypernova

A collapsarhypernova is a theoretical type of hypernova, which is an exceptionally energetic supernova explosion. The term "collapsar" refers to the central object that forms during the supernova, a rapidly rotating black hole. The collapsar model suggests that if a massive star, typically between 25 and 60 solar masses, collapses under its own gravity, and if this core is rotating sufficiently rapidly, it can form a black hole surrounded by an accretion disk.

This accretion disk feeds material onto the black hole, generating powerful jets of plasma that are launched from the poles of the star. These jets, traveling at relativistic speeds, are believed to be the source of the immense energy released in a collapsarhypernova. The interaction of these jets with the surrounding stellar material is thought to produce the observed luminosity and spectral characteristics of certain hypernovae.

The collapsar model is a leading explanation for long-duration gamma-ray bursts (GRBs), which are intense bursts of gamma radiation detected from distant galaxies. The jets from a collapsar are predicted to produce gamma rays as they break out of the star. While the collapsar model successfully explains many observed features of hypernovae and GRBs, direct observational evidence for the black hole and accretion disk remains challenging due to their small size and extreme distances. Ongoing research aims to further refine theoretical models and search for observational signatures that can confirm or refute the collapsar hypothesis.
