We aim to use the methods of binary population synthesis (BPS) to study the ultraviolet upturn (UVX) in the spectra of giant elliptical galaxies with emphasis being placed on those binary channels which could lead to the formation of stars that can account for it. This project will combine Sukyoung Yi's single star population synthesis methodology with that of Zhanwen Han's binary population synthesis methods in order to provide a more coherent study of the origin of the UV upturn, the focus being on sdB stars as the possible source of the UV upturn. The primary approach of the project will be to explore the UV upturn, with sdBs included, for several different metallicities in order to examine the UVX in composite populations.
