Most models of the formation of Jupiter assume explicitely or implicitely that the planet formed in a relatively massive nebula of roughly solar composition. While this "early" formation seems to be consistent with astronomical observations showing the quick dissapearance of circumstellar disks, it poses several problems.
One of them is migration: A proto-Jupiter in a massive disk would have been prone to very rapid migration. The second is halting planetary growth: numerical simulations have shown that gap opening does not prevent gas accretion onto the planet, which should therefore grow to large masses. A last one is the presence of abundant argon in Jupiter's atmosphere.
We present a scenario in which Jupiter and the other giant planets are supposed to have formed late, in a depleted protosolar nebula. We show that our model avoids the problems described above and discuss its consequences for the origin of the Solar System.
