Question

how a star die explain in brief

Answer 1

Stars expand as they grow old. As their core runs out of hydrogen and then helium, the core contacts and the outer layers expand, cool, and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. A star's life span and eventual fate are determined by the original mass of the star.

Life span:
The most massive stars have the shortest lives. Stars that are 25 to 50 times that of the Sun live for only a few million years. They die so quickly because they burn massive amounts of nuclear fuel.

For example, Betelgeuse (the second-brightest star in Orion) is a red supergiant star that is about 20 times more massive than the Sun. It is about 14,000 times brighter than the Sun and burns nuclear fuel at a rate 14,000 times faster than than that of the Sun. The Sun will live about 7,000 times longer than a massive star like Betelgeuse.

Stars like our Sun live for about 10 billion years. Stars less massive than the Sun have even longer life spans.

Fate of a Star:
A star will become either a black dwarf, neutron star, or black hole, depending on how massive it was. .

Sun-like Stars (Mass under 1.5 times the mass of the Sun) --> Red Giant --> Planetary Nebula -->White Dwarf --> Black Dwarf

Huge Stars (Mass between 1.5 to 3 times the mass of the Sun) --> Red SuperGiant --> Supernova --> Neutron Star

Giant Stars (Mass over 3 times the mass of the Sun) --> Red SuperGiant --> Supernova --> Black Hole


EVOLVED STAR
An evolved star is an old star that is near the end of its existence. Its nuclear fuel is mostly gone. The star loses mass from its surface, producing a stellar wind (gas that is ejected from the surface of a star). Older stars produce more stellar wind than younger stars.

Answer 2

when more gas dust particles and more other types of elements are combine each other then after a long time these matter are made up of a star then in these star the process of nuclear fusion is continuously becoming then in these star are made up of the giant star after a long time. and hydrogen gas is converted into helium gas due to which after some time these star's hydrogen gas is converted into helium gas completely and star's fuel. in this situation star are old in his age or he is waste his half life and left his half life in is that when the completed converted into a big giant star and completely red then these star's nuclear fusion pro is unbalanced due to which the star is blasted and expensed in the space time which is known as a supernova after supernova the stars are changed in two bodies which is known as white draft it is in white colour and a nuclear star after changing in these states these stars are converted into a black hole. the star are converted into black hole it is a topic on other but I can't say that how a star converted into a black hole because you are only asked that how a star die. so bro this is some lines that how to a star die and alive in his life on the other words a star life cycle.
