What is left over after a supernova?

supernova remnant, nebula left behind after a supernova, a spectacular explosion in which a star ejects most of its mass in a violently expanding cloud of debris. … The stars became bright enough to be visible in the daytime.

What elements are formed by a supernova?

The chemical elements up to iron – carbon, oxygen, neon, silicon and iron – are produced in ordinary stellar neucleosynthesis. The energy and neutrons released in a supernova explosion enable elements heavier than iron, such as Au (gold) and U (Uranium) to form and be expelled into space.

What three things can be left behind by a supernova?

Type II supernovae usually leave behind one of three objects:
  • A neutron star.
  • A pulsar (this is just a spinning neutron star, really)
  • A black hole.

Do supernovae leave anything behind?

The most powerful stellar blasts in the universe may not always destroy stars in explosive supernovas as scientists had thought, but instead leave behind a remnant “zombie star,” astronomers say.

What elements are formed during and after supernova?

The elements formed in these stages range from oxygen through to iron. During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

What is left after a star dies?

Stars die because they exhaust their nuclear fuel. … Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’. What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – or, if there’s sufficient mass, a black hole.

What is left after a supernova of what used to be a blue star with a very large mass?

The giant star then sheds most of its envelope, losing mass until it can no longer continue nuclear fusion. At this point, it becomes a white dwarf star, composed primarily of carbon and oxygen. Eventually, the secondary star also evolves off the main sequence to form a red giant.

What happens after a Nova?

It collapses and causes a massive explosion. What’s left afterward is a stellar remnant — a neutron star, black hole, or white dwarf. Our sun will most likely become a white dwarf at the end of its life.

What remains of a massive star after it explodes as a supernova quizlet?

After a Supernova the star will become a Neutron Star, giving off very little light. If it is big enough the Star could collapse in on it self making it a Black Hole. We have recently found that anything with enough gravity can collapse in on it self and become a Black Hole, so even you or I could.
