Abstract
The evolution of the composition plays a key role in shaping the observable properties of galaxies. Modeling chemical evolution enables us to connect star formation, gas flows, and feedback to observed abundance trends across cosmic time. We use chemical evolution model RAMICES II to mimic galaxy M33. The radial abundances in oxygen and iron predicted by the fiducial model are compared to observational data in the galaxy. We also explore the effect of different assumptions around the evolution of M33. The fiducial model predicts a radial abundance of -0.035 ± 0.001 dex kpc-1 for oxygen and -0.056 ± 0.001 dex kpc-1 for iron, both in good agreement with the data, except for observed oxygen abundances in PNe. We also find that radial flows induced by angular momentum, and a low surface density cut-off in the Schmidt-Kennicutt law have significant effects on the metallicity gradient.
