The Evolution of Intermediate-Mass Binaries

I discuss three aspects of binary stellar evolution, based on (1) an exploration of a large number (5550) of conservative Case A evolutionary models by Nelson & Eggleton (2001), (2) a rather smaller number (150) of conservative Case B evolutionary evolutionary models by Han, Tout & Eggleton (2000), and (3) an attempt by myself to understand the circumstances in which very non-conservative Case C evolution can lead, through a common-envelope phase, to short-period highly evolved systems containing one or two white dwarfs and/or hot subdwarfs.
