DDO metal abundances of high-luminosity late-type stars in galactic open clusters.

Abstract (from CDS):

Result. from UBV and DDO photometry are presented for 54 high-luminosity late-type stars in the fields of 23 open clusters. The probability of cluster membership for each observed star is evaluated using two independent photometric criteria. It is found that 32 stars are very likely cluster members, the remaining ones being almost ceterainly field objects. The recently improved calibrations of the DDO system have been used to derive MK spectral types, effective temperatures, and metallicities, while E(B-V) color excesses have been determined through known photometric and spectroscopic procedures. The DDO metallicities range between values typical of moderately metal-poor ([Fe/H]≃ -0.3) to moderately metal-rich ([Fe/H] ≃ 0.2) clusters. The masses of the cluster giants range between 1 and 4 solar masses, with the scatter within a cluster being less than 1 solar mass.
