Asteroseismology of the Hyades with K2: first detection of main-sequence solar-like oscillations in an open cluster

TL;DR

This study reports the first detection of solar-like oscillations in main-sequence stars within an open cluster, using K2 data to enable asteroseismic analysis of Hyades cluster stars.

Contribution

It presents the first observation of solar-like oscillations in main-sequence stars in an open cluster, expanding asteroseismology to cluster environments.

Findings

Detected solar-like oscillations in two F-type Hyades stars

Enabled asteroseismic analysis of main-sequence stars in an open cluster

First such detections in the Hyades cluster

Abstract

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.
