摘要：
We present the result of a search for Cepheids in the Local Group dwarf irregular galaxy Pegasus. We identified 20 Cepheid stars with periods 0(.)(d)6 < P < 15(.)(d)3, compared them with previously published Cepheids, and carried out an accurate completeness analysis in order to obtain the fraction lost. Using their period-luminosity relation, we obtain a distance for Pegasus of 950 +/- 30 kpc.
