Bengt Gustafsson (astronomer) on Wikipedia
Abstract: The atomic chemical composition of the Sun departs systematically from that of most other solar-type stars in that its ratio of volatiles (like the biogenic elements) to the refractories is higher by about 10%. What does this tell about the formation and evolution of the Solar System? Scenarios in terms of different nucleosynthesis, early formation of the pre-solar nebula, of the evolution of the proto-planetary disk, of the engulfing of planets, and of other processes within the system will be considered. Implications, if any, on the habitability of the Solar System will commented on.
