STOCHASTIC 2-D GALAXY DISK EVOLUTION MODELS. RESOLVED STELLAR POPULATIONS IN THE GALAXY M33

摘要

We improved the stochastic 2-D galaxy disk models (Mineikis 86 Vansevicius 2014a) by introducing enriched gas outflows from galaxies and synthetic color-magnitude diagrams of stellar populations. To test the models, we use the HST/ACS stellar photometry data in four fields located along the major axis of the galaxy M33 (Williams et al. 2009) and demonstrate the potential of the models to derive 2-D star formation histories in the resolved disk galaxies.
