Course description and aims

In this course, I pick up various astronomical objects in the universe: stars and galaxies, and lecture their birth and evolution together with physical processes governing the phenomena and their emission mechanisms. Thanks to the recent developments in observing the universe, our understanding of astrophysical phenomena has advanced in leaps and bounds.
The goal of this course is to utilize knowledge in mechanics, electromagnetism, thermal and statistical mechanics, quantum mechanics, etc. learned so far to explain the astrophysical phenomena obtained with the latest observations from a physics viewpoint.

Student learning outcomes

At the end of this course, students will be able to
1) Explain underlying physics of astrophysical phenomena in the universe.
2) Explain the phenomena revealed by the latest space observations.
3) Explain characteristics of black-body radiation, spectral lines from atoms and ions, which are important to understand the universe.


Universe, astrophysics, stars

Competencies that will be developed

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

Class flow

Lectures will be held by explaining the latest observational results using slides, and explaining phenomena on the blackboard. The slides are basically written in English with partial Japanese translation. This course will be given in Japanese, but English is also used when foreign students attend.
