Comparisons with observations

Conclusion

What is planet population synthesis

I Create planets from firstprinciples

I Predict propertiesI 2 models:

I IL modelI AMB model

I Focus on AMB model

I First principle model

Conclusion

I From first principles predict planets

I Evolution from planetary disk to planets

I Construct disk from first principles

I Include time evolution of disk

I Calculate planetesimal evolution

I Calculate planetesimals to planets including accretion ofplanetesimals and gas
