The Distance to the Fornax Dwarf Galaxy Using Red Clump Stars and the Discrepancy between Red Clump and Tip of the Red Giant Branch Distances

I determine a distance to the Fornax dwarf galaxy using stars in the red clump and at the tip of the red giant branch. They are in very good agreement, with μ 0 = 20.66 mag. Comparing the magnitudes of the tip of the red giant branch and of the red clump in Fornax, Carina, and the Magellanic Clouds, I propose a possible solution to the problem of the discrepancy between these two types of distance measurements.
