Photoelectric photometry and period analysis of selected Delta Scuti stars in Praesepe
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 Stroemgren photometry and theoretical and empirical calibrations. The observations are available in electronic form at CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.70.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html
