My Fairy Tale
- Oligarchic growth produces 4-5 cores of 10-15 Earth-masses in the Jupiter-Saturn zone.
- The innermost and outermost (+/- 1) start to accrete gas and open gaps.
- Waves generated at resonances shock gas between gas planets. Gas is removed.
- Jupiter-core-core-Saturn system stable for 700Myr.
- Cores (Uranus and Neptune) get scattered outwards.
- Interaction with trans-Saturniuan disk leads to
- the Lunar Late-Heavy Bombardment.
- Uranus and Neptune evolve to current orbits.
