    Abstract

    We present a search for variable stars in the Fornax dwarf galaxy covering an area of half a square degree. We have ∼30 epochs of VIdata. We found and determined periods for more than 500 RR Lyrae, 17 anomalous Cepheids, and six Population II Cepheids. In addition we have 85 candidate long-period variables, the majority of which were previously unknown. We estimate that the average metal abundance of RR Lyrae stars is [Fe/H] ≃ -1.6 dex.
