Conclusions

• Giant planet systems can play an important role in the formation of terrestrial planets:
  • This is because they can excite eccentricities of the embryos.
  
  
• If embryos are excited:
  • Fewer planets will grow
  • They will tend to grow at the inner edge of the system.
  
  
  
• Giant planets can also greatly effect the habitability of terrestrial planets.
  • The terrestrial planets can be dry.
  • They can have a high impact flux.
