No expertise in the matter, but I assume the question is how our solar system formed with gas giants in the outer orbits and rocky planets in the habitable zone and how common this might be around other stars. The final paragraph of the conclusion has some hints.
I am particularly interested in why we are on a planet that is so rich in phosphorus and the final phrase about "delivery of chemically enriched material to planetary atmospheres" is a real tease.
- svachalek 5y agoThe Bae et al paper linked in that paragraph (https://iopscience.iop.org/article/10.3847/2041-8213/ab46b0 https://iopscience.iop.org/article/10.3847/2041-8213/ab46b0) (note Bae is cited second on OP paper) actually has quite a bit more to do with the way planets settle into orbits, based on study of this same system. As a fellow layman I haven't read it in detail but it looks fascinating, will check it out later. These are really interesting papers and full of pics and diagrams, although the math is beyond me.
