As of now, more than 1800 planets have been detected outside of our own solar system. However, a comprehensive picture of how they were born remains lacking. The reason is that the process of planet formation involves complicated interaction between solid materials, gaseous medium, and magnetic fields. To study this process, numerical simulations on high-end computing facilities are required.

In this research program, we focus on studying how kilometer-sized celestial objects called planetesimals were formed in such a complex environment. We will use a public computer program called the Pencil Code to simulate a system of numerous pebbles and boulders moving inside a magnetized gas disk. We will observe how these solid bodies can be concentrated to form larger bodies by a mechanism called the streaming instability. To achieve this goal, we need to further implement several state-of-the-art numerical techniques for the Pencil Code. These new implementations will help us produce a pilot study of planetesimal formation in a magnetized gas disk.
