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.
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
planet formation, protoplanetary disks, planetesimals, dust
Lectures will be given in the first half of the course. In the second half, students will present papers on related topics.

Grades will be based on in-class participation and discussion (50%) and presentation (50%). Your participation and discussion grade will be determined based on your questions and comments to the instructor and presenters. Students who never ask a question in all classes will fail the course.
