HD 45364: forming a 3:2 resonant system

The Dynamical Origin of the Multi-Planetary System HD45364

Considering the formation of the system and avoiding the capture into a 2:1 resonance, it is predicted that the eccentricities of the two planets around HD 45364 have significantly lower eccentricities than the previously-published orbits. Give it a few years for the orbits to evolve, and this can be tested.

A new scenario for the origin of the 3/2 resonant system HD45364
http://arxiv.org/abs/1307.1822

Further study of how this system formed... type III migration seems to be out, a combination of migration types I and II seems to work.
