SIMULATION OF A JOVIAN PLANET UNDERGOING GAS ACCRETION

Fabian Marcel Menezes

Resumo


To understand the process of planet formation in the Solar System, or any other stellar system, we need to comprehend the interaction between forming planets and the protoplanetary disk. This work presents a study of the interaction of the protoplanetary disk with the protoplanet and the consequent types of orbital migration that can occur. To verify this, numerical simulations were performed using the magneto-hydrodynamics code FARGO3D. Five simulations were made with a 2-Jupiter-mass planet in the protoplanetary disk. The only parameter varied was the initial radial position with the aim of verifying the influence of this parameter on the behavior of planetary migration. As a result of these simulations we find that the initial radial coordinate is a very significant parameter in how the planet interacts with the gas in the disk and in the formation of gas gaps.
