Anomalous Cepheids in Crater II

Year: 2025

Type: article

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.
