The answer depends on the original mass of the star. If it was not too massive, it will shrink to a dwarf star. If it was sufficiently massive, it will explode as a nova. A really massive star, exploding as a supernova, will leave behind either a neutron star, a pulsar or a black hole.
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
The core is necessary for a star's existence, it's the engine that keeps it from collapsing. When this engine runs out of fuel or its fuel vanishes, gravity overcomes and contracts the star until matter from the radiative zone is compressed enough to start fusing hydrogen again to counterbalance gravity.
Yes, all stars run on a limited suppliy of fuel - mainly hydrogen. Some stars burn it very quickly but reach high temperatures, while other lower mass stars burn their fuel more slowly, lasting for longer, but burn at cooler temperatures.
If the sun had 10 times its current mass, it would burn through its fuel faster and evolve into a red supergiant star. When it runs out of fuel, it may go through a supernova explosion, leaving behind a dense core called a neutron star or potentially collapsing into a black hole.
Lots of things do NOT happen. Better read an article on star formation and find out what DOES happen.
they become super novas and explode
This will happen when the star starts to run out of hydrogen fuel.
When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star
It is believed that they usually start from the gravitational collapse of a massive star - once it runs out of fuel.
Some massive stars reach a supernova state once they have exhausted all their nuclear fuel.
It happens when a star 8 times bigger than the sun(if the star is bigger it uses up more fuel/hydrogen)starts to run out of fuel and turns helium into heavier elements and when it finally reaches iron it collapses and turn into a neutron star, then a black hole.
Such a star will first have a supernova explosion, due to instability in the nucleus. Then it will most likely turn into a black hole.
A neutron star is already the remains of a massive star that has run out of fuel.

their is a star trun so that it gone right their is a star trun so that it gone right
