\label{fig:twin}Power density spectrum of KIC 11725564 (gray), a seismic “twin” of KIC 9246715 (red). Both power spectra are smoothed with a boxcar of \(1/50\) of the large separation. The modes in KIC 11725564, a secondary red clump star, have \(\Delta\nu\) and \(\nu_{\rm{max}}\) which very nearly match KIC 9246715. They are less noisy and have larger amplitudes than the modes in KIC 9246715, making this star a useful asteroseismic comparison.
