The Cepheids Variable Stars Population in the Local Group Dwarf Irregular Galaxy Pegasus
Published online by Cambridge University Press: 01 December 2006
Abstract
We present the result of a search for Cepheids in the Local Group dwarf irregular galaxy (DIG) Pegasus. We identified 20 Cepheid stars with periods 0d.6 < P < 15d.3. We have compared them with previously published Cepheids and we have carried out an accurate completeness analysis in order to obtain the fraction of them which are lost. Using their period-luminosity relation we obtain a distance for Pegasus of 950±30 Kpc.
