Study of changes in the periods of population II Cepheids in globular clusters I: M2
Abstract:265 magnitude estimates for three the Cepheids V1, V5 and V6 in the globular cluster M2 were made using plates from the Sternberg Astronomical Institute photographic plate collection. The data, which complemented published data, allowed us to improve the light elements of these Cepheids; no systematic trend in pulsation periods were found.
