Interacting Binary Stars and Stellar Populations
Spectroscopic analysis of stellar populations is widely used to understand the history of many systems including globular clusters, nuclear star clusters, dwarf galaxies through to giant galaxies over a wide range of redshifts. In this talk I first explore aspects of stellar population fitting, focussing on the effects of interacting binary stars on the yields and hence the spectra of early-type galaxies. The second part of the talk concentrates on what we know about supernovae type Ia and the importance of understanding their contributions to the chemical evolution of galaxies and stellar populations.
