The Role of Giant Planets in Terrestrial Planet Formation

Hal Levison, Luke Dones, Craig Agnor, Robin Canup, & Martin Duncan

---

We have modeled the late stages of planet formation under the gravitational influence of a variety of giant planet systems.

The giant planet systems:

• Were real or taken from Levison, Lissauer, & Duncan (1997).
• Were stable for at least 1 billion years.

The 100 embryos were:

• Mass = 0.04 .
• Eccentricities and sin(i) < 0.02.
• Uniformly spread from 0.5 to 3.1 AU. May miss Mercury .

The integrations:

• Direct N-body using SyMBA.
• Assumed `perfect' accretion.
