EW Aqr, a non radial Delta Scuti pulsator.
Abstract
Analysis of six nights of differential photometry for the δ Scuti star EW Aqr gives periods of 0d09664, 0d1087 and 0d2121 with the semi-amplitudes of 0.013, 0.010 and 0.007 mag, respectively. The ratios of these periods and the beating shown in the light curves indicate that this star is a non-radial pulsator.
