WebA hypernova explosion is the most powerful explosion that we know of whilst a kilonova is still very powerful but no where near the strength of the former stellar explosion. A … Hypernovae are thought to be supernovae with ejecta having a kinetic energy larger than about 10 joule, an order of magnitude higher than a typical core collapse supernova. The ejected nickel masses are large and the ejection velocity up to 99% of the speed of light. These are typically of type Ic, and some are … Ver mais A hypernova (sometimes called a collapsar) is a very energetic supernova thought to result from an extreme core-collapse scenario. In this case, a massive star (>30 solar masses) collapses to form a rotating black hole emitting … Ver mais Models for hypernova focus on the efficient transfer of energy into the ejecta.
