follow-up observations. The bright B3V-type star HD 142883 is found to be an eclipsing binary in a triple star system. We observe a series of frequencies at large multiples of the orbital frequency in BW Aqr that we tentatively identify as tidally induced pulsations in this well-studied eccentric binary system. We find that the faint eclipsing binary EPIC 201160323 shows rapid apsidal motion. Rotational modulation signals are observed in 13 eclipsing systems, the majority of which are found to rotate non-synchronously with their orbits. ]{} [The K2 mission is a rich source of data that can be used to find long period eclipsing binary stars. These data combined with follow-up observations can be used to precisely measure the masses and radii of stars for which such fundamental data are currently lacking, e.g., sub-giant stars and slowly-rotating low-mass stars.]{}

Introduction
============

Apart from the Sun and a few nearby stars, detached (i.e., non-interacting) eclipsing binaries (DEBS) provide the only means to measure accurate, model-independent masses and radii for normal stars. Using high-quality multi-wavelength photometry and high-resolution spectroscopy, masses and radii for stars in DEBS can be measured to $\pm 0.5$% or better . Spectral disentangling techniques also make it possible to
