Description

We present the first comprehensive catalog of variable stars in the Leo II dwarf spheroidal galaxy. We have identified 148 RR Lyrae type variables, of which 140 were amenable to derivation of variability parameters with our data. We have also confirmed the existence of four anomalous Cepheids as identified in previous studies. The average period of the RR Lyrae ab variables (0.62 days), the fraction of c variables (0.24), and the minimum period of the RR Lyrae ab variables (0.51 days) all define Leo II as an "Oosterhoff intermediate" galaxy. We have used the properties of these variables to derive a metallicity for Leo II of approximately [Fe/H]=-1.9.
