* Supernovae are caused by core collapse: Supernovae occur when the core of a massive star runs out of fuel and collapses under its own gravity. This triggers a violent explosion that blasts the star's outer layers into space.
* Neutron stars are already collapsed: Neutron stars are the remnants of a supernova. They are formed when the core of a massive star collapses to a point where it is held together by the strong force, squeezing protons and electrons together to form neutrons. This is already the endpoint of the core collapse process.
* Neutron stars are incredibly dense: Neutron stars are incredibly dense, with a mass roughly 1.4 to 3 times that of our Sun packed into a sphere only about 20 kilometers across. This extreme density makes it incredibly difficult for further collapse to occur.
However, neutron stars can still "go supernova" in a different way:
* Accretion-induced collapse: If a neutron star is part of a binary system, it can accrete matter from its companion star. This accretion can increase the neutron star's mass to a point where it becomes unstable and collapses into a black hole. This process can be accompanied by a powerful explosion, sometimes referred to as a "supernova" or "hypernova," though it differs from the typical core-collapse supernova.
So, the short answer is: While a neutron star won't undergo a core-collapse supernova like its progenitor star, it can become unstable and collapse into a black hole through accretion, leading to a different type of explosion.
