Astrophys. Suppl. Ser. 129 9 1998 1998A&AS..129....9P Clusters, open Photometry Stars, variable delta Scuti open clusters and associations: individual (Praesepe) stars: oscillations Photoelectric photometry of seven Delta Scuti stars in Praesepe was secured. Three of them were observed simultaneously at observatories located at different longitudes. Period analysis has been carried out for each star with different computing packages and the results compared to those in the literature. Their physical characteristics have been determined from the Stromgren photometry and theoretical and empirical calibrations.
