Variable stars in nearby galaxies . ⋆ II . Population I and II Cepheids in Field A of IC 1613

Abstract

The light curves of Cepheids and other variable stars in Field A of IC 1613, obtained with a CCD and no filter (Wh photometry), have been analyzed. It is possible to separate first overtone from fundamental mode population I Cepheids taking into account the pulsation amplitude, the shape of the light curve and the period. The expected separation is verified… (More)
