What is the end result of a supernova?

Question

or, to start with, where does a supernoca come from? and where does it go

Answer 1

It depends on the mass of the star in question. For example, a star is born, it grows old, it gets larger (Red giant stage) and it dies. Depending on its mass and newly discovered turbulence inside a star before collapse, it will either go supernova and create a planetary nebula and reduce to a white dwarf, or go supernova, continue to collapse and turn into a black hole. It all depends on the mass of the star, and the amount and directionality of the turbulence inside the star's core.

Answer 2

A supernova is what a massive star goes through when it stops undergoing nuclear fusion. There are a few end results, the most massive of the stars become black holes after going supernova. Less massive stars become neutron stars, an extremely dense star with a diameter of only 10-20 Km, they're so dense they usually have a mass of 1.5 to over 2 times the mass of our sun. Two other possible end points for stars that go supernova are pulsars, which are rotating neutron stars, and magnetars, which are neutron stars with an extremely strong magnetic field.

A star like our sun will not go supernova, it'll go nova and eventually shrink down to a white dwarf.

Answer 3

There are different types of supernovae. All of the different types involve the core of a massive star collapsing to a neutron star or a black hole. The "flash" of the supernova comes from the former outer layers of the star, which have an enormous amount of energy put into them in the form of photons and neutrinos. These outer layers get blown off into interstellar space at high speeds---initially, thousands of kilometers per second. As this ball of hot gas expands, it gets brighter because its surface area is increasing, even as it cools. Then, after several weeks, it cools and dims. Eventually, after hundreds of years, these gasses slow down and become part of the interstellar medium, a "supernova remant". If a neutron star is left behind, it will likely become a pulsar. The neutron star or black hole is sometimes in a binary system with another star. The neutron star or black hole can be ejected from this binary system at hundreds of kilometers per second, enough to throw it out of the Galaxy.

Answer 4

Depends on the size of the star that went supernova.

It can become a neutron star, black hole.

I'm not sure if supernova produces white dwarfs. I don't think so.

Answer 5

Wikipedia can tell you all about it.
