A star becomes either a white dwarf, neutron star, pulsar, or black hole based on how massive the start is. Red dwarfs and yellow medium sized start like our Sun become white dwarfs and expel their outer atmospheres to create planetary nebulas. Larger stars like giant blue or even supergiant stars become neutron stars or black holes depending again on how big the star is. A pulsar is just a spinning neutron star. The biggest stars the really massive supergiants don't even leave a trace when they go supernova. I hope this answers your question.

Answer: A star's life time depends on how much gas it has built up during it's formation.

Answer: This depends mainly on the star's mass. More massive stars get hotter (due to the greater gravitational attraction), and burn their fuel faster.

What factor determines how a star lives?

I assume you mean, "how long a star lives". That depends mainly on the star's mass, with more massive stars using up their fuel way faster than less massive ones.

How long star live?

Stars live different lengths of time, depending on how big they are. A star like our Sun lives for about 10 billion years, while a star which weighs twenty times as much lives only 10 million years, about a thousandth as long.
