  The Hyades open cluster was targeted during Campaign 4 (C4) of the NASA K2
mission, and short-cadence data were collected on a number of cool
main-sequence stars. Here, we report results on two F-type stars that show
detectable oscillations of a quality that allows asteroseismic analyses to be
performed. These are the first ever detections of solar-like oscillations in
main-sequence stars in an open cluster.
