What do collapsed stars form?

Answer 1

Collapsed stars form black holes, which have such a strong gravitational pull that not even light can escape.

They can also form Neutron Stars, which are so dense that one grain of sand in the form of a neutron star could throw the earth off course.

As well as nebulae, which are massive clouds of gas and dust.

Answer 2

The massive stars forms a neutron star when they collapse but stars having more than 9-10 solar masses produces a black hole when they die .

Black holes are formed when a massive star have very less fuel or receive some extra matter in such a way that it no longer raise its core temperature, in both cases the star's core temp. isn't high enough to prevent its collapsing under its own weight . Sometimes stars having comparatively less mass survive the explosion and forms a neutron star .

Answer 3

Heavier elements require a nova or supernova to form. The main sequence stars mostly turn hydrogen into helium, but they also form the lighter elements up to iron. After that, far more intense forces are required to fuse atomic nuclei. The stellar collapse forces the nuclei to fuse.

Answer 4

A supernova forms a great number of things. In medieval times, astronomers and scholars would occasionally notice a new star appear in the sky. Since all medieval scholars normally wrote and spoke Latin, they called them "Nova Stellarum", which is Latin for "New Star". Clever and tricky, these medieval scholars!

We now know that these are actually "old stars" in the process of dying. A "supernova" is an especially bright and powerful "old star" as it explodes. What does it form? Everything around us! The great mass of all matter in the universe is hydrogen gas, the simplest element. In the core of a star, hydrogen fuses into helium, the second most common element. And that's all there is; hydrogen and helium, from one end of the early universe to the other.

But toward the end of their short lives, very massive stars begin to collapse, and the pressure and temperature of the stellar core shoots up. In that extreme environment, the helium itself can fuse into carbon, and can form oxygen and nitrogen and other light elements. Only during the last few moments of a star's existence, when the pressures and temperatures reach a peak, can even more massive elements be forced to fuse - creating all of the heavier elements like iron, or lead, or gold. Once the star begins fusing iron into really heavy elements, the star explodes and destroys itself in a titanic supernova explosion.

Some of the mass, the heavy elements, are blasted back into space, where they drift in space for eons until they fall into a stellar nebula, and become part of a new solar system. In fact, every atom of iron in the hemoglobin of your blood was formed in the core of a star dying in the explosion of a supernova many billions of years ago!

The mass of the star that wasn't blasted back into space is crushed into the core of the star, where it forms either a neutron star or a black hole, depending on the mass of the original star and how the explosion proceeded.

Our Sun, an entirely average star, is too small to become a nova or supernova.

Answer 5

It depends on the mass of the star. In most cases it will leave behind a neutron star. The most massive stars leave behind a black hole.

Answer 6

It could become a black hole or a neutron star.

Answer 7

black holes
