Abstract:
The core
accretion scenario is used here as the starting point of a 3-D model
for the runaway gas accretion that completes the event of gas giant
planet formation. Calculations start with a planetary embryo accreting
gas from its neighborhood. The initial gas velocity distribution is set
to keplerian and Coriolis force is included, simulating the disk
hydrodynamical environment as viewed from the reference point of the
forming planet. The work is currently in its early stages, and for now,
the code involves solving the Navier-Stokes equations considering only
hydrodynamics and gravity. Further on, radiative transfer,
thermodynamics, magnetic fields and second-order dynamical interactions
(e.g., resonances) with the disk will be added, aiming toward a more
realistic 3D model of the process.
