Anomalous Cepheids in Crater II

Abstract Fifteen Anomalous Cepheid (ACeph) candidates were recently identified in the dwarf galaxy Crater II via an extended survey done with the Dark Energy Camera at the 4 m Blanco Telescope at Cerro Tololo Inter-American Observatory (CTIO). Using various Period–Luminosity relationships found in the literature, we anchor these candidates to the nearby RR-Lyrae stars’ distances to confirm 14 of the candidates as not only being ACephs, but as confidently belonging to Crater II rather than the field within the line-of-sight.
