How do stars die?

Answer 1

When a star begins to run out of fuel,the center of the star shrinks and the outer parts of the star expands star become a red giant or supergiant.All main sequence stars eventually become red giants or supergiants.However what happen next depend on the mass of the star's as Exploring the Live of Stars shows.When a star run out of fuel, it becomes a White Dwarf,a Neutron Star,or a Black Hole.
When a star begins to exhaust its hydrogen supply, its life nears an end. The first sign of a star's old age is a swelling and reddening of its outer regions. These are called red giants.The Sun, which is a middle-aged star, will probably swell to a red giant in 5 billion years, vaporizing Earth and any creatures that may be on its surface. When all its fuel has been exhausted, a star cannot generate sufficient pressure at its center to balance the crushing force of gravity. The star collapses under the force of its own weight. Very massive stars can go supernova and leave behind a neutron star or black hole. Small or average-sized stars (like our Sun) leave behind a white dwarf.

Answer 2

Because in the core of the star, hydrogen is being fused into heavier elements

this provides radiation energy that keeps the star "alive" and provides a force to prevent the star collapsing into itself.

eventually, after many million/billions of years, the hydrogen runs out in the core of the star

so no more energy can be produced, and the star swells up into a red giant

and then, depending on the mass of the star, it either goes supernova or becomes a white dwarf. Or sometimes a black hole/supermassive black hole.

Answer 3

When a star begins to exhaust its hydrogen supply, its life nears an end. The first sign of a star's old age is a swelling and reddening of its outer regions. These are called red giants.The Sun, which is a middle-aged star, will probably swell to a red giant in 5 billion years, vaporizing Earth and any creatures that may be on its surface.

Very massive stars can go supernova and leave behind a neutron star or black hole. Small or average-sized stars (like our Sun) leave behind a white dwarf.
A star will "die" if it runs out of fuel. Once it can no longer produce energy through nuclear fusion, there is not enough radiation pressure; the star will collapse (gravitational collapse). The final result can be any of the following, depending on the star's remaining mass:

• White dwarf
• Neutron star
• Black hole

Read the Wikipedia article on each of the three if you want more details.

Answer 4

Stars are mainly made up of hydrogen, which is used as a fuel to produce energy. There is a huge amount of hydrogen, but it will eventually get used up one day, and the star will begin to die out.

Answer 5

There are so many stars visible in the night sky. When some of them disappear, usually its because something is between it and Earth, but in many cases it is because it has finally burned out.

Answer 6

an average star spends 90 percent of its life as a hydrogen-burning, main-sequencestar. Once the hydrogen fuel in the star's core is depleted, it evolves rapidly and dies

Answer 7

When stars "age", they spend their fuel source in a nuclear reaction (usually nuclear fusion).
