Scientific paper

Four δ Scuti stars were observed with the HERCULES fibrefed Échelle spectrograph at Mount John University Observatory, New Zealand. These observations were analyzed by looking at the radial velocity variations as given by a cross correlation technique as well as spectral line moment variations. These results were compared to published photometric studies of these stars to see if the modes identified in the photometry were also present in the spectroscopic data obtained.
