Formation of solar system analogues : I. Looking for initial conditions through a population synthesis analysis

Population synthesis models of planetary systems developed during the last ∼15 yr could reproduce several of the observables of the exoplanet population, and also allowed us to constrain planetary formation models.We present our planet formation model, which calculates the evolution of a planetary s...

description Population synthesis models of planetary systems developed during the last ∼15 yr could reproduce several of the observables of the exoplanet population, and also allowed us to constrain planetary formation models.We present our planet formation model, which calculates the evolution of a planetary system during the gaseous phase. The code incorporates relevant physical phenomena for the formation of a planetary system, like photoevaporation, planet migration, gas accretion, water delivery in embryos and planetesimals, a detailed study of the orbital evolution of the planetesimal population, and the treatment of the fusion between embryos, considering their atmospheres. The main goal of this work, unlike other works of planetary population synthesis, is to find suitable scenarios and physical parameters of the disc to form Solar system analogues.We are specially interested in the final planet distributions, and in the final surface density, eccentricity and inclination profiles for the planetesimal population. These final distributions will be used as initial conditions for N-body simulations to study the post-oligarchic formation in a second work. We then consider different formation scenarios, with different planetesimal sizes and different type I migration rates. We find that Solar system analogues are favoured in massive discs, with low type I migration rates, and small planetesimal sizes. Besides, those rocky planets within their habitables zones are dry when discs dissipate. At last, the final configurations of Solar system analogues include information about the mass and semimajor axis of the planets, water contents, and the properties of the planetesimal remnants.
