This course introduces basic knowledges about astronomy and astrophysics, and gives introductory reviews on physical bases required to understand phenomena in the Universe. With this course, students get to know that even the cosmic events of extraordinary scales can be understood from fundamental physics laws. Furthermore, this course aims to nourish practical capabilities to solve real-world physics problems through exercises to obtain order-of-magnitude estimations of physical quantities in astrophysical phenomena by applying physics laws.
【Goals】 To learn the basic concepts and knowledges required to understand the current views on the Universe and unresolved problems. To understand astrophysical phenomena based on physical principles.
【Thema】 The Universe is the most intellectually fascinating object to the human kind. Researches on the Universe started from the sun and the moon, then extended to the planets and stars, and then beyond the Milky Way out to its horizon. Get familiar with the Universe from the view point of physics.
Radiation processes, electromagnetic waves, stellar structure, stellar evolution, compact objects, galaxies, Hubble's law, Big Bang, cosmic background radiation, gravitational wave, inflation, dark matter, dark energy

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
No textbook is specified. The course materials are uploaded at OCW.
