Abstract

´╗┐We analyzed new photometry of HD 213616, showing that, instead of being a W Ursae Majoris eclipsing binary, it is a multimode delta Scuti star of relatively high amplitude. Three independent pulsation modes were identified in a Fourier analysis of the photometry, in addition to several combination pulsation frequencies.
