講義の概要とねらい

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.

到達目標

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

キーワード
