A Suite of Classical Cepheids Tied to the Binary Cluster Berkeley 58 and NGC 7790.

MAJAESS D. and TURNER D.G.

Abstract (from CDS):

The classical Cepheids CE Cas A, CE Cas B, CF Cas, and CG Cas are likely members of the binary open cluster comprising NGC 7790 and Berkeley 58. The clusters are of comparable age and in close proximity, as deduced from differentially dereddened UuBPBVGRP photometry, and Cepheid period-age relations. Gaia DR3 astrometric and spectroscopic solutions for the clusters are likewise consistent. Conversely, the seemingly adjacent open cluster NGC 7788 is substantially younger and nearer.
