can anyone tell me about various stages of life of a star? when does a neutron star, supernova, pulsar form?

utkarsh009 said:the riddler mentioned the best ever sites with all information and also interactive quizzes. thank you! but there is no information about pulsar. and for pulsar qraal just did what i had expected. thanks to you too! wow now i won't be confused in this part, at least. and again the quizzes on the sites were very good.
The life cycle of a star begins with the collapse of a cloud of gas and dust, known as a nebula, under its own gravity. This forms a protostar, which eventually becomes a main sequence star, where it will spend most of its life. Depending on its mass, a star will eventually run out of fuel and either become a white dwarf, neutron star, or black hole.
Stars produce light and heat through the process of nuclear fusion. In the core of a star, hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the form of light and heat. This process continues until the star runs out of hydrogen fuel.
The lifespan of a star is primarily determined by its mass. The more massive a star is, the shorter its lifespan will be. Other factors that can impact a star's lifespan include its composition, rotation rate, and whether it is part of a binary system.
Stars can die in a variety of ways, depending on their mass. Low to medium mass stars, like our sun, will eventually run out of hydrogen fuel and become a red giant, shedding its outer layers and leaving behind a white dwarf. High mass stars, on the other hand, will end their lives in a spectacular supernova explosion, leaving behind either a neutron star or black hole.
Technically, no. Once a star has exhausted all of its fuel, it cannot reignite and continue its fusion process. However, some stars, such as white dwarfs, can undergo a type of nuclear fusion called carbon fusion, which temporarily provides them with a new source of energy. This is not considered a true "resurrection," but rather a brief extension of the star's lifespan.
