WebAstronomers estimate that some red dwarf stars will burn for up to 10 trillion years. The smallest red dwarfs are 0.075 times the mass of the Sun, and they can have a mass of up to half of the Sun. ... Giants and supergiants form when a star runs out of hydrogen and begins burning helium. As the star’s core collapses and gets hotter, the ... WebJun 27, 2014 · As Joan.bdm pointed out, stars have an interior volume, the burning zone down towards the core in which the pressures are high enough for fusion to take place. Probably should call it the burning volume The burning volume is the volume in which fusion can occur. Fusion occurs once a specific threshold of heat and pressure have been reached. does rhubarb come back every year

By the time silicon fuses into iron, the star runs out of fuel in a matter of days. The next step would be fusing iron into some heavier element but doing so requires energy instead of releasing it. The star’s iron core collapses until forces between the nuclei push the brakes, then it rebounds. See more Astronomers estimate that the universe could contain up to one septillion stars – which in numbers is 1,000,000,000,000,000,000,000,000.
