Testing Asteroseismic Scaling Relations with Interferometry

Abstract

The asteroseismic scaling relations for the frequency of maximum oscillation power, vmax , and the large frequency separation, Δν , provide an easy way to directly determine the masses and radii of stars with detected solar-like oscillations. With the vast amount of data available from the CoRoT and Kepler missions, the convenience of the scaling relations has resulted in their wide-spread use. But how valid are the scaling relations when applied to red giants, which have a substantially different structure than the Sun? Verifying the scaling relations empirically requires independent measurements. We report on the current state and future prospects of interferometric tests of the scaling relations.
