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 kilometer-sized solid bodies called planetesimals.
到達目標
1) Understand the physical processes governing the evolution of gas and dust in protoplanetary disks, including the solar nebula
2) Become familiar with order-of-magnitude estimates --- how to understand physics underlying complex phenomena
キーワード
planet formation, protoplanetary disks, planetesimals, dust

授業の進め方
Lectures will be given in the first half of the course. In the second half, some studies on thermal evolution of dust particles in the solar nebula are shown as examples of real researches in this field. The second half will be given by NAKAMOTO.
