Well, our Sun is a metal-rich star and scientists are quite sure that
two stars ending as supernova preceded the formation of our Sun (so it
has a "mother" and a "grandmother"). There are metal-deficient and
metal-poor stars, which also gives an indication about the number of
generations. The question is was the "grandmother" made up of
primordial material? Or are there more than 2 stars after the big bang
that led to the formation of the Sun? Is there really a way of
knowing? Does a great-grandmother exist? Are there even more
ancestors? 13.7 billion years is a long time and large stars burn up
in a few 100 million years or less. Any insights on this?
