What happens if the core remnant of a supernova has a mass that is greater than 3 solar masses?

What happens if the core remnant of a supernova has a mass that is greater than 3 solar masses?

If the core has a mass greater than about 3 solar masses, even neutron pressure is not sufficient to withstand gravity, and it will collapse further into a stellar black hole.

What happens to the core after a supernova?

The outer layers of the star are blown off in the explosion, leaving a contracting core of the star after the supernova. The shock waves and material that fly out from the supernova can cause the formation of new stars. If the star was much bigger than the Sun, the core will shrink down to a black hole.

What happens to the core of the supernova if it is more than 5 solar masses?

When the core is more massive (Mcore > ~ 5 solar masses), nothing in the known universe is able to stop the core collapse, so the core completely falls into itself, creating a black hole, an object so dense that even light cannot escape its gravitational grasp.

What happens if the core of a star that goes supernova is greater than 2.8 solar masses?

A star with a mass between 8 and 20 solar masses will undergo nuclear fusion in the core all the way up to iron (Fe) before exploding in a supernova explosion. If the remaining core mass is more than 1.4 solar masses and less than 2.8 solar masses then this incredibly dense object will form.

How much mass is left after a star goes supernova?

The core that remains after a supernova explosion is an extremely dense ball of neutrons. If its mass does not exceed three solar masses it will remain a neutron star (Begelman & Rees, 43).

What stellar remnant will the sun become?

As such, when our Sun runs out of hydrogen fuel, it will expand to become a red giant, puff off its outer layers, and then settle down as a compact white dwarf star, then slowly cooling down for trillions of years.

What’s left behind after a massive star supernova?

Answer: A neutron star that is left-over after a supernova is actually a remnant of the massive star which went supernova. Once the neutron star is over the mass limit, which is at a mass of about 3 solar masses, the collapse to a black hole occurs in less than a second.

Can our sun go supernova?

The Sun as a red giant will then… go supernova? Actually, no—it doesn’t have enough mass to explode. Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now.

What happens in the core of a massive star just before it goes supernova?

Just before core-collapse, the interior of a massive star looks a little like an onion, with shells of successively lighter elements burning around an iron core. Up until this stage, the enormous mass of the star has been supported against gravity by the energy released in fusing lighter elements into heavier ones.
