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.
