Project Progress

In collaboration with Jonathan Lunine, Quinn and Raymond have performed integrations of planetary embryos as they form the terrestrial planets. They have explored the dependence of the chemical composition of the resulting terrestrial planets on the properties of the planet formation scenario. They have extended this work to look at scenarios in planetary systems with “Hot Jupiters”. They have found that planets with compositions suitable for habitability can form in these situations. They have also performed higher resolution simulations of the volatile delivery process, and have discovered that with more lower mass protoplanets planets are formed that have lower eccentricities and a less stochastic distribution of volatile elements.
