Course description and aims

Planets in the solar-system are considered to be formed in protosolar nebular around protosun. Recent optical and radio observations have revealed existence of proto-planertary disks and planets around other stars. How did our solar-system and these extra-solar planetary systems form and evolve? This course will first provide basic knowledge about observational astronomy. Next, basics of optical, infrared and radio astronomy will be introduced, together with those of stars, planets, mocluar clouds, and proto-planetary disks. Lastly theories of planetary formation, evolution, interior, and atmosphere will be overviewed.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand the basics of optical, infrared, and ratio astronomy, and planet formation theory
2) Apply these knowledge to interpret properties of the solar-system and extrasolar planetary systems


optical and infrared astronomy, radio astronomy, planet formation theory, solar system, extrasolar planets, proto-planetary disk

Competencies that will be developed

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

Class flow

At the beginning of the class, a summary of the previous lecture is given. Then the main points of the day's lecuture are given, and students are asked to provide solutions to some of the questiones as necessary.
