basic characterisation of the eclipse properties, e.g., depth and width.

At the time of writing, there are approximately 200 DEBS that have masses and radii measured to a precision of 2% or better [@2015ASPC..496..164S]. This sample is dominated by short-period systems ($P \loa 10$d) in which the components of the binary system are forced to co-rotate with the orbit. This makes it difficult to study phenomena such as interior mixing processes that can have subtle effects on the evolution of normal stars, but which may be disrupted by rapid rotation, particularly for sub-giant and giant stars.

We have conducted our own search of the Kepler K2 data from campaigns 1, 2 and 3 and characterised the stars in these binaries in some detail using modelling of the Kepler K2 light curve plus existing optical and infrared photometry. Our study is motivated by the opportunity to study in detail stars of a type for which little fundamental accurate data are currently available. We have concentrated on bright stars with well-defined eclipses and long orbital periods that are ideal for detailed characterisation using high-resolution spectroscopy, but also discuss some other DEBS of interest that we have found in our survey.
