Do we really need to worry about binary stars?
JJ Eldridge

This answer to this question depends on who you ask but in nearly all parts of astrophysics the answer should be yes. Yet most stellar evolution models that are widely used today assume that stars are single. This is at odds with our growing understanding that most stars are in binary systems close enough the two stars can interact and experience very different evolution to that of single stars. I will discuss how the Binary Population and Spectral Synthesis (BPASS) code provides a tool to be able to include these different evolutionary pathways when studying stellar systems. I will show the importance of accounting for binary interactions by discussing a few examples. These will include stellar populations in HII regions, open clusters and globular clusters, galaxies near and far and the variety of both electromagnetic and gravitational transients.
