Collapse of iron core
WebApr 7, 2024 · Without the support of degeneracy pressure, the cold solid iron stellar core, analyzed under hydro-static equilibrium conditions, is supposed to collapse under self-gravitation into a Black Hole. WebFeb 12, 2024 · There is a strong evidence that core-collapse supernovae are explosions of massive stars, but the explosion mechanism is a decades-long standing question. We have shown that the exlosion is likely a thermonuclear explosion triggered by the collapse of of the star' iron core.

Web3 Core-collapse supernovae. Core-collapse supernovae, like some epochs in the early universe, are neutrino-dominated dynamical systems. In these supernovae essentially all the gravitational energy released during collapse escapes in the form of intense neutrino fluxes emerging from the newly-born neutron star.
