Transition of the stellar initial mass function explored using binary population synthesis

The stellar initial mass function (IMF) plays a crucial role in the determination of the number of surviving stars in galaxies, of the chemical composition of the interstellar medium and of the distribution of light in galaxies. A key unsolved question i

AGB evolution and nucleosynthesis at low-metallicity constrained by the star formation history of our galaxy

We construct a binary population synthesis model to constrain the AGB evolution models from the star formation history of the Galaxy through the comparisons of model stars with observed extremely metal-poor stars. The binary population model includes th
