Resumen:
We develop a semi-analytical model for computing planetary systems
formation based on the core instability model for the gas accretion
of the embryos and the oligarchic growth regime for the accretion of
the solid cores. With this model we consider different initial
conditions to generate a variety of planetary systems and analyse
them statistically. We explore the effects in the formation of
assuming different discs, in the context of a surface density profile
motivated by similarity solutions for viscous accretion discs,
analising not only different initial discs profiles but also a large
range of discs masses and sizes according to the last results
of observations in protoplanetary discs. We also analyse
the effects of type I and II regimes of planetary migration, which
were found to play fundamental role in reproducing the distribution
of observed exoplanets.
