According to the classical accretion models, giant planets are formed through the planet core formation in the disk of planetesimals. When a core attains a determined (critical) mass, it is capable to capture the residual gas of the protoplanetary disk which will constitute its envelope. Therefore a giant planet is formed. The critical point of this scenario is to adjust the times of the solid core formation, capture of the gas and the planetary migration to the disk lifetime. To construct a complete model which considers all these processes is a hard and challenging task as well.The purpose of this project is to continue the previous studies done during the masters programme, when the formation and the evolution of the solid planetary core were investigated. It is expected to complete this project, developing the study of planetary formation with the gas accretion simultaneously with planetary migration of type II that only occurs in giant planet systems.
