Exoplanets Hot Jupiters? Who ordered those?!
Okay, where did all the Hot Jupiters come from? Cannot form inside the snow/frost line Formed further out & migrated A nice little (8 MB) of one example, by Phil Armitage, U Colorado
Also, planetary scattering (Nice model...) Bottom line: current locations of exoplanets may have little to do with where they formed. Late Heavy Bombardment but LHB disputed...
