WebLifespans for main sequence stars have a vast range. Whilst our Sun will spend 10 billion years on the main sequence, a high-mass, ten solar-mass (10M Sun) star will only last 20 million years (2.0× 10 7 years) on the main sequence. A star with a only half the mass of Sun can spend 80 billion years on the main sequence. http://spiff.rit.edu/classes/phys370/lectures/post_highmass/post_highmass.html
