Planets are formed from gas and dust in protoplanetary disks. Collisional growth and sedimentation of dust grains as well as the gas dispersal are important processes which lead to the planet formation and affect the orbital evolution evolution of planets. Meanwhile, chemical evolution of gaseous and icy components in the disks is important to understand the origin of materials in our Solar System and exoplanetary systems. In this course these physical and chemical processes in protoplanetary disks together with related recent infrared and radio observations of the disks will be lectured.
This course aims to understand the physical and chemical processes related to the evolution of materials in our Solar System and exoplanetary systems. Especially, formation of star and planetary systems, evolution of dust particles, gas dispersal processes, chemical evolution of gaseous and icy materials in the disks, its relation with the chemical properties of the objects in our Solar System, and physical and chemical properties of exoplanetary systems will be lectured. Also, the course aims to
understand recent infrared and radio observations of protoplanetary disks.
