Question

Quizplus · Accepted Answer

A supernova type II can leave behind a shell of hot, expanding gas with a neutron star at the center. This is because a supernova type II occurs when a massive star runs out of nuclear fuel and collapses, causing the core to become incredibly dense and hot. This can result in a massive explosion that blows off the outer layers of the star, leaving behind a hot, expanding shell of gas. If the remnant core of the star has a mass greater than three times the mass of the sun, it will collapse further and become a neutron star, which can be detected through its pulsations or by observing the radiation emitted from the surrounding gas.
