What forms when a massive star collapses after a supernova?

What forms when a massive star collapses after a supernova?

Supernovae are thus essential to life. After a core collapse supernova, all that remains is a dense core and hot gas called a nebula. When stars are especially large, the core collapses into a black hole.

What happens to a supernova after it explodes?

The outer layers of the star are propelled into space by the expanding shock wave creating a supernova remnant, a type of nebula. This material is now available to be recycled into another star, planet, or possibly eventually a life form billions of years down the road.

What forms when the most massive stars collapse?

When a star goes supernova, its core implodes, and can either become a neutron star or a black hole, depending on mass.

What does a supernova collapse into?

The collapse may cause violent expulsion of the outer layers of the star resulting in a supernova, or the release of gravitational potential energy may be insufficient and the star may collapse into a black hole or neutron star with little radiated energy.

What happens to a massive star when its core collapses?

Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity. While the core collapses, the outer layers of material in the star to expand outward. The star expands to larger than it has ever been – a few hundred times bigger!

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.

What are the effects of a supernova?

Supernovae, the explosions of stars, have been the main focus. A really nearby event — 30 light-years away or closer — would induce a mass extinction from radiation destroying the ozone layer, allowing lots of ultraviolet radiation through to damage life on the surface.

Which does a massive star enters the stage of becoming a supernova?

Stage 2 – The massive star then becomes a Red Supergiant and starts of with a helium core surrounded by a shell of cooling, expanding gas. Stage 4 – The core collapses in less than a second, causing an explosion called a Supernova, in which a shock wave blows of the outer layers of the star.

What triggers a supernova explosion quizlet?

This is when a Massive Star uses up all of its fuel, the core will then turn into iron (which is like a poison to a star) and the star will explode. The Star will continue to become more and more unstable which will cause a nuclear reaction in the core causing the Star to go Supernova.

What are the results of a supernova explosion of a massive star?

When the star explodes, it shoots elements and debris into space. Many of the elements we find here on Earth are made in the core of stars. These elements travel on to form new stars, planets and everything else in the universe.

Which is the leftover remnant of a supernova?

A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away. Astronomers and careful observers saw the supernova in the year 1054.

What makes a star collapse into a supernova?

Stars live in a delicate balance between two opposing forces: the gravity trying to make them collapse inwards and the thermal pressure of nuclear fusion exerting an outward pressure.

How big is the core of a supernova?

The core reaches its minimum size of about 10 km, but then it begins to rebound. As it does so, shock waves are driven into the stellar material that is also trying to fall in to the center. After this rebound the core will again collapse, but this time it is more or locked into place as a fully formed neutron star.

What happens when the core of a star collapses?

“Within a massive, evolved star (a) the onion-layered shells of elements undergo fusion, forming a nickel-iron core (b) that reaches Chandrasekhar-mass and starts to collapse. The inner part of the core is compressed into neutrons (c), causing infalling material to bounce (d) and form an outward-propagating shock front (red).
