Chiaki Kobayashi, Ralph Sutherland How galaxies did form and evolution? - to answer this unsolved problem, we are simulating the formation and evolutionary history of galaxies in the Universe, including star formation, supernovae feedback, and chemical enrichment. Comparing the spacial distribution of elements within galaxies with observations, we will examine fundamental physical processes that drive galaxy formation. ...

... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...
