Formation of second generation stars

Our solar system contains all known stable elements. Since many of them can neither have been formed in the Big Bang nor by fusion in stars in the solar cycle, they must have a different origin. As far as we understand today, the heaviest elements can only be formed in supernova explosions that generate a high flux of free neutrons. These can be absorbed by lighter nuclei giving rise to heavier elements. This means that our sun must belong to the second generation of stars.
