Terrestrial Formation in These Synthetic Systems Model late stages of terrestrial planet formation:

• Keep everything the same except the giant planet system
  Six different ones:
  ........... No giant planets. ..........................
  
  
• Start with 100 embryos of M=0.04 and 0.5<a<3AU. No Mercury! .
• Evolve in gas free environment.
  
  
• Integrated for 2x10⁸ years using direct N-body techniques.
  • Impacts lead to mergers.
