What is an exploded star?

Answer 1

"Exploded" is not actually the proper term for your question.

When a star runs out of hydrogen to burn, it cools off, and shrinks. The fusion of hydrogen creates helium, which requires much more pressure and heat to be fused. The only reason the sun doesn't collapse right now is due to the heat created by the hydrogen fusion. The heat balances out the gravity from all of that mass. But when the fusion reactions stop, all of that helium will cool, and as the dead star cool, all of that matter (helium) will get drawn closer and closer together. As this happens, it will get hot again. Eventually, the pressure and heat will meet the requirement to start fusing helium.

Helium fusion releases much more energy than hydrogen fusion. The result is that the helium-fusing star (Commonly called a "red giant.") will expand much more than a yellow star, because the heat generated is greater than the gravitational field that holds the matter together. When our sun becomes a red giant, the earth will be devoured as will Mars, and possibly even as far as Uranus. However, this expansion facillitates the release of heat. The red giant will cool and shrink. After shrinking, it will get hotter again, and expand again. This cycle will continue until there is no longer enough helium in the core to sustain fusion. A star can shed as much as 80% of its mass in the red giant phaze, because some of the outer layers can't keep up with the shrinking core, and these outer layers get pushed out into space.

One could consider the red giant expansion to be an explosion, but I doubt that this is what you met.

Instead, I believe you were referring to a supernova, which is actually an implosion, not an explosion.

If a dead star has the mass of 1 1/2 times the mass in its core that the sun has right now, but less than 3 solar masses, it undergoes another collapse, becoming a neutron star. If the solar mass is three or greater, then it will become a black hole. Either condition will cause a supernova.

A supernova is caused when the core of a star collapses at the atomic level. This implosion releases a huge amount of energy, which is the supernova, and is responsible for the creation of every single element in the universe heavier than iron.

Answer 2

a star is a heavenly body of helium and hydrogen where hydrogen turns in to helium through nuclear fusion. now that creates a great amount of energy (like lots of nuclear bombs ). this keeps on going in the star for millions of years (like what is happening in the sun today) but after a long time it becomes difficult for the star to withhold so much of energy thus it starts expanding and becomes a red giant in which the core of the star shrinks whereas the the outer side expands and then comes the final part when star explodes this is called supernova or the "exploded star" the core keeps shrinking and might turn in to "black hole".
hope that answers ur query.

Answer 3

it does not necesserely turn into a supernova, a supernove is mearly a stage in a stars life where it rapidly performs nuclear fusion making a lot more heat and energy, but the fate of most stars is a nebulae, pretty much it is just a cloud of plasma ,decomposed crap leftover from the stars previous life, another unlikely occurence is that it continues performing nuclear fusion with its materials it keeps goin on and on from hydrogen to helium etc all the way to iron which is not able to be fused any more, as the fuel rapidly turns to iron the gravity put out from the mass of the collapsing star crushes the matter beyong all recognition , making a singularity in the center( the center of the colapsed star with extreme gravitational forces that not even light can escape, i can go on for alot longer about the 2 kinds of black holes and theories of time tavel, if you want to know all that stuff then email me and ill explain

Answer 4

A supernova is an exploding star. After that, it is either a blackhole or a dwarf star. A blackhole's gravity is so superior that it sucks in light, as well. A dwarf star is a very very dense and small star that gives off a very small amount of light.

Answer 5

The explosion itself is called a 'supernova.' Afterwards, either a neutron star or a black hole is all that's left. White dwarf stars are *not* what supernovae leave behind.

Answer 6

properly,have u heard of massive bang theory.Its a theory conventional by technique of a majority of scientiest that asserts that the photo voltaic platforms and the galaxies were shaped after a large explosion in the area.perhaps it is what those scientiest meant by technique of declaring that we are genuinely searching decrease back in time on seeing an exploding fashionable man or woman in the sky.(for extra referance style huge bang theory in google.satisfied getting to comprehend)

Answer 7

Hi. The remains? Either a white dwarf, neutron star (or pulsar) or a black hole.

Answer 8

A bunch of little pieces of an old star.


To be serious, why don't u just google it?

Answer 9

a supernova.
