In the last couple of years the detection of gravitational waves from merging binary black holes and neutron stars has sparked a significant amount of work to try to understand their astrophysical origin. As future observing runs of the LIGO and VIRGO observatories (together with upcoming installations) are expected to detect hundreds of mergers in the coming decade, strong constrains will be placed on proposed formation scenarios. In this talk I will review the different ways in which binary stars in the field are expected to produce merging compact objects, focusing in particular on models that invoke either common envelope evolution or rotationally induced mixing, and how upcoming observations will be used to distinguish between these. I will also discuss how these processes impact the formation of various sources of electromagnetic waves, such as X-ray binaries, luminous red novae and various types of supernovae.
