Oligarchic Growth
Kokubo and Ida (1998)
Fills in the gap between
`Run Away Growth'
and
`Late Stages' of planet formation.
The largest few objects at any given time are:
of comparable mass
separation is ~
10R
H
~
f(M,a)
.
So, as the system evolves:
Number of big guys decreases
Their masses increase
Their separation increases
WARNING:
Oligarchic growth was only modeled at 1AU.
However, between 5 and 10AU there is room for 3 to 5
Uranus-sized objects (15
