Course description and aims

This course deals with the physics of gas and dust evolution in protoplanetary disks. Protoplanetary disks are gas disks surrounding young stars, and the solids in the disks are the building blocks of planets and other solid bodies. We will learn how micron-sized dust particles form (and do not form) kilometer-sized solid bodies called planetesimals.

Student learning outcomes

1) Understand the physical processes governing the evolution of gas and dust protoplanetary disks
2) Become familiar with order-of-magnitude estimates --- how to understand physics underlying complex phenomena
3) Improve your skills in critically reading scientific papers

Keywords

planet formation, protoplanetary disks, planetesimals, dust

Competencies that will be developed

✔ Specialist skills Intercultural skills ✔ Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Lectures will be given in the first half of the course. In the second half, students will present papers on related topics.
