Abstract

Abstract: Stellar population synthesis based models of the Milky Way play a crucial role in understanding and interpreting observational data from large surveys of the Milky Way. We describe the basic theoretical framework for modelling the Milky Way and discuss algorithms for generating a synthetic sample of stars out of such models. Next, we discuss how asteroseismology can be used to test and possibly refine theoretical models of the Milky Way. As an application we test the ability of Galaxia to reproduce the properties of stars observed by the NASA Kepler mission. We present some preliminary results. We find that Galaxia can reproduce the photometric properties of the sample. Additionally, it can also reproduce the distribution of average asteroseismic parameters and radius. In future, comparing the mass distributions will allow us to test the Galactic models more rigorously.
