What will happen to a star once all its fuel is gone?
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.
When does a star enter its third stage?
A star enters its third stage, known as the red giant phase, when it exhausts the hydrogen fuel in its core and starts fusing helium into heavier elements. During this phase, the star expands and becomes much larger in size.
Why is the sun or the star eventually die?
A star eventually uses up all of it's hydrogen in nuclear fusion. They fusion of hydrogen into helium is what makes the star glow bright and hot. When all the helium is fused, the star collapses inward on itself, and becomes a small "white dwarf" star, essentially a pile of "stellar embers". That's the end of a star's life.
What causes the changes in a star?
each star is made up of hydrogen and the source of energy and heat in stars is nuclear fusion of hydogen nuclei into helium at a tempreature of around 6 m celsius.after a particular period when all the hydrogen will be converted into helium then because of intense gravitational pull the star will begun to collapse under its own gravity and at a particular tempreature again the fusion of helium into lithium starts this phase of sun is known as white dwarf. if the weight of any star is equivalent to the mass of our sun then that star will enter into white dwarf phase after red giant phase, and if the mass of staris more than the mass of sun then after redgiant phase star will change into neutron star or pulsar and then finally end up as blaack hole.for e.g black hole observed in sirius constellation 100 light years far from earth
What happen to a sun-like star after it has used up all the fuel in its core?
Towards the end of its life, a star with a size similar to ours will expand to a red giant star as the core contracts and heats up and the hydrogen fuel supply is consumed. It will eventually lose the outer layers and all that will be left is a core, a white dwarf reminant that will slowly cool over millions of years.

When does a star enter third stage?
When almost all of the hydrogen atoms within its core have fused into helium atoms. Source: holt earth science
What is the last stage of nuclear fusion?
A neutron star is already a dead star it can produce no more energy, although massively dense it will just continue to radiate its energy out into space until there is nothing left. There is an alternative ending for a Neutron Star and that is, if it was a part of a binary system or had enough mass collect on it could collapse further to create a Black Hole.
Where iron comes from?
Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum
Where is iron made mostly from?
Iron is fused within a star's core. When sufficient iron has accumulated and it begins to fuse, the energy of that fusion is too great and the star explodes creating all the heavier elements.up ya bum
Why would white dwarf stars have less amount hydrogen?
A white dwarf is the remnant of a star that has fused all the hydrogen and helium in its core, leaving mostly carbon and oxygen nuclei.
