Stars are fundamental to galactic archaeology, both as sites of stellar nucleosynthesis and as unevolved 'fossils' preserving a chemical record of the galaxy at their time of formation. Both require a fundamental understanding of how stars work: how they transport material and the processes by which they synthesis isotopes. I will discuss some of the challenges facing stellar modellers, and how they can be addressed in an era where asteroseismology and multidimensional simulations can help to develop our understanding of what is going on deep within stellar interiors. I will highlight some of the nucleosynthesis that can happen at low metallicities -- in particular the so-called intermediate neutron capture process -- and how it impacts our understanding of the production of the elements in the early stellar generations.
