Hey Philip, thank you for the talk and very interesting work! I was wondering how similar would Mars be compared to Proto-Earth in terms of compositions, since it is not shown on your result figure. Thank you!
Thanks! In the simulation I showed (at the time I've shown) we don't have a very good Mars-analog. The most Mars-like embryos tend to be somewhat similar to the proto-Earth, with correlation coefficients of ~0.4–0.6. They tend to have more mass coming from the 1.2–2 au region than the proto-Earth does, which is approximately what I would expect. This material would presumably give Mars an appropriately more ordinary-chondrite-like composition.
