Anomalous Cepheids in Crater II.

COOKE M.J. and VIVAS A.K.

Abstract (from CDS):

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.
