Chemodynamical Simulations of Galaxies
Chiaki Kobayashi (University of Hertfordshire)

The formation and evolutionary histories of galaxies are imprinted in the
stellar populations, namely, in the elemental abundance ratios.
I am simulating chemodynamical evolution of galaxies using my
hydrodynamical code that includes star formation and chemical enrichment
from core-collapse and Type Ia supernovae and AGB stars.
We then succeeded in reproducing various observations such as the
elemental abundance ratios in Galactic bulge, disk, and thick disk, radial
gradients of ellipticals, and mass-metallicity relations of galaxies.
I will also discuss some observations that are not reproduced with current
simulations, and show some new results on nucleosynthesis of primordial
stars and AGN feedback.
