Issue Date: | 2015 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Number: | 86 | First Page: | 338 | 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. <P /> | URI: | http://hdl.handle.net/20.500.12386/23374 | ISSN: | 0037-8720 | Bibcode ADS: | 2015MmSAI..86..338G | Fulltext: | open |
