Feb 15, 2017 at 18:34 | comment | added | dmckee --- ex-moderator kitten | @Rob, I think we may be answering different question. Your "the Sun is the product of the ∼ billion stars" answers how many stars have contributed mass to what is not the sun (and I'm sure you're right). The question I gave a lower limit to is more along the lines of "What is the average number of stars that a nucleon current in the sun has been in before?" (and I've ignored the deep philosophical difficulty of tracking the identity of a nucleon through nuclear transformations, too, but the OP didn't seem ready for that). | |
Feb 15, 2017 at 9:30 | comment | added | ProfRob | I think this is a vast underestimate because it ignores that mixing takes place in the ISM on timescales that are short compared with the lifetime of the Galaxy. Many, if not most, of the $\sim 10^9$ massive stars that were born billions of years before the Sun in our Galaxy have contributed nuclei to the solar system. | |
