Abstract: This explanatory visualization shows the results of a state-of-the-art 3D simulation of supernova explosion and neutron-star birth. It is a rare instance where the full stellar evolution of an object, including the physics of the convection and the radiation, has been simulated in three dimensions. Among the highlights is the deep core that is shrinking after explosion due to neutrino cooling and deleptonization on its way to becoming a cold, compact neutron star. There is also evidence of inner proto-neutron star convection, perhaps the site of magnetic dynamo action that can turn a pulsar into a magnetar. An exterior view shows the blast wave, which cocoons the newly-birthed neutron star, moving at ∼10,000 km/s. Additionally, a reusable pipeline was developed, which leverages state-of-the-art tools for scientific data analysis and visualization resulting in high-quality renderings.
