Abstract
We present results on the study of the Andromeda XIX (And XIX) dwarf spheroidal companion of M31, based on time-series photometry obtained with the Large Binocular Telescope (LBT). The LBT-based CMD of And XIX reaches V ̃ 26.5 mag. We have identified 35 variables in the galaxy, they include 24 RR Lyrae stars, 8 Anomalous Cepheids, 2 binaries, and 1 SX-Phoenicis candidate.
