Research Abstract |
We study a new mechanism to explain the formation of gas giant planets. A gas giant planet is formed while a protoplanetary disk evolves. We introduced some elementary processes (e.g., self gravity) into the numerical program to simulate the evolution of a protoplanetary disk. Using the developed numerical program, we simulated the evolution of a protoplanetary disk and found that some vortices with the mass of a gas giant planet are formed in a protoplanetary disk. The vortices are thought to evolve into a gas giant planet.
