Scientific paper

The results of photometry of disk stars in the galaxy IC 1613 are presented. The position of the red giant branch allowed us to measure the distance to the galaxy (m-M)=24.53+/-0.10, as well as metallicity ([Fe/H] = -1.75) and age (lg t =~ 10.1) of disk stars. The variation of the surface density of red giants depending on the distance from the center of the galaxy has been found. Rough estimate of the total number of red giants in the galaxy and total disk mass are presented.
