The aim is to establish the location of the hot end of the stochastic convective excitation mechanism and to what extent it may overlap the delta Scuti/gamma Doradus instability region. A simple but effective autocorrelation method is described which is capable of detecting low-amplitude solar-like oscillations, but with significant risk of a false detection. The location of the frequency of maximum oscillation power, $\\nu_{\\rm max}$, and the large frequency separation, $\\Delta\\nu$, is determined for 167 stars hotter than 6000 K, of which 70 are new detections. Results indicate that the hot edge of excitation of solar-like oscillations does not appear to extend into the delta Scuti/gamma Doradus instability strip.", "revisions": [ { "version": "v1", "updated": "2020-08-14T11:43:23.000Z" } ], "analyses": { "keywords": [ "solar-like oscillations", "hot limit", "kepler photometry", "delta scuti/gamma doradus instability region", "delta scuti/gamma doradus instability strip" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
