Abstract:

Precise studies on the Galactic bulge, thick disk, and multiple populations of globular cluster require stellar model with alpha enhancement and various helium contents. It is also important for extra- Galactic study to have alpha enhanced population synthesis. For this purpose we expand PARSEC model from solar-scaled composition to alpha enhanced mixtures. The new model closes the gap between the observation and model prediction on the RGB bump. Recently we also bring a homogeneousand stellar bolometric correction databse online, which provide a SED-based extinction and different atmosphere models.
