Asteroseismology of the Hyades with K2: first detection of main-sequence solar-like oscillations in an open cluster,
Monthly Notices of the Royal Astronomical Society, Vol. 463, Issue 3
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.
