Main sequence (dwarf) stars have only a certain amount of internal fuel available within their hot cores. When the hydrogen fuel has all turned to helium, the stars begin to die and to produce a number of other different kinds, the whole process commonly known as stellar evolution. Because higher mass stars use their hydrogen fuel much more quickly than lower mass stars, those of higher mass live shorter lives. The Sun has a 10 billion year main sequence lifetime (of which half is gone). The most massive stars live only a couple million years, the least massive for trillions, so long that no star with a mass less than about 0.8 solar masses has ever died in the history of the Galaxy. From theory, we calculate that such a 0.8 solar mass star should live for about 13 billion years. The Galaxy should be about as old as its oldest stars, and is thus about 13 billion years old.
well theyre stars... which is burning gas...so they were never actually alive so they cant die. but if you wanna say they die when they are no longer bright then yes at some point they will run out of gas to burn and "die". keep in mind that doesnt mean they become black holes as some "dead stars become that when the pressure isnt in balance with gravity but thats another question about black hole formation for the siencey part of yahoo answers
Low mass crimson-dwarf stars could burn for many trillion of years till which era they slowly cool off and become smaller. ultimately billions of years extra the celeb will thoroughly burn out, completely dropping all of its luminosity.
