Role of Giant Planets (cont)

Global Trends:

• Each giant planet systems has it unique way of exciting the embryos.
  • Requires a complete understanding of the system to predict.
• The eccentricities of the embryos determine what kind of terrestrial planetary system forms
  • Larger eccentricities produces fewer terrestrial planets
  • In dynamically excited systems, the terrestrial planet forms close to the star.
    • Due to simple geometry.
• Which leads us to:
