• Week1：Galactic Universe

  We will learn how mankind’s worldview of the galactic Universe has evolved. We will then provide an overview of the dynamical structure of the entire Galaxy and the realm of the surrounding galactic Universe.

  
  

  • 1-0. Introduction
  • 1-1. Invitation to Galactic Archaeology
  • 1-2. Development of Cosmology ： From Geocentrism to Heliocentrism
  • 1-3. Development of Cosmology ： Galaxies and the Island Universe
  • 1-4. The Galaxy : Overall View
  • 1-5. The Galaxy : Interstellar Gas and Star Formation
  • 1-6. The Local Group
  • 1-7. Cluster of Galaxies and Large-Scale Structure of the Universe
  • 1-8. Galactic Rotation
  • 1-9. Spiral Structure of Galaxies
• Week2：Life, Death, and Material Cycles of Stars

  We will learn about the general characteristics, evolution and death of the stars making up galaxies. We will also understand that stars are factories of new matter, and the relation between their material cycles and galactic evolution.
  

  • 2-0. Introduction
  • 2-1. The Realm of the Stars
  • 2-2. Stellar Color and Spectral Type
  • 2-3. Color Magnitude Diagram of Stars
  • 2-4. Stellar Chemical Abundance and Metallicity
  • 2-5. Stellar Structure: Why Do Stars Shine?
  • 2-6. Stellar Evolution and Death
  • 2-7. Stellar Death and the Origin of Elements
  • 2-8. Material Cycles and Chemical Evolution of Galaxies
  • 2-9. Explore the Past and Present of Galaxies through Stars
• Week3：Galaxy Formation and Evolution

  We will learn how our Galaxy’s formation and evolution is currently described by derivations from the analysis of old stellar systems in the Milky Way. In addition, we will understand the general concept of galaxy formation based on observational information from the Andromeda Galaxy and other general galaxies.
  

  • 3-0. Introduction
  • 3-1. Exploration of Old Stars
  • 3-2. Development of the View of Galaxy Formation History
  • 3-3. Formation of the Halo
  • 3-4. Formation of the Disks : Thick disk
  • 3-5. Formation of the Disks : Thin disk
  • 3-6. Formation of the Bulge
  • 3-7. Formation of Galactic Satellite Galaxies
  • 3-8. Formation of the Andromeda Galaxy
  • 3-9. Formation and Evolution of General Galaxies
• Week4：Dark Matter and Galaxy

  We will learn about the dark matter that dominates the dynamical structure of such galaxies, the evidence for its existence, and its role in galaxy formation. We will then learn about problems with the current standard theory of the identity of dark matter, and future prospects.

  • 4-0. Introduction
  • 4-1. Dark Matter in Galaxies (Ⅰ)
  • 4-2. Dark Matter in Galaxies (Ⅱ)
