Abstract:
    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.
