Photometry of southern Cepheids in 2002
Abstract:A total of 6083 photoelectric observations in the BVIC system, obtained between February and April 2002, are presented for 122 Cepheids located in the southern hemisphere. The main function of the photometry is to provide data that can be used to establish new epochs of maximum brightness for the Cepheids as input for the scientific study of their period changes, as well as to establish current light elements for the variables. The primary cause of period changes in Cepheids is evolution through the instability strip.
