So, what am I talking about?

• Recall that between ~4 and ~10AU, we find that oligarchic growth can make gas giant planet cores if disk mass ~5X minimum mass nebula.
  
  
• When cores reach ~10 they should start to accrete gas from solar nebula.
  
  
• There is ~ 70 of solids in this region.
• Cores are about 10-15 4-5 cores.

• Largest core(s) start to accrete gas from solar nebula, they disrupt oligarchic growth.
  
  
• Remaining cores gravitationally scattered by growing gas giants.
  
  
• Their orbits circularized by trans-planetary disk.
  
  
• In roughly 50% of the cases we have run, we get a reasonable solar system.
