Intermediate-band photometry of late-type stars. IX. Two Hyades-like clusters.
Abstract
Observations of NGC 2423 and 2482 are discussed. NGC 2423 has a dozen early G-type to late K-type giants. Although the reddest and brightest giant needs confirmation of cluster membership, the remaining stars show a color-luminosity distribution very similar to that found previously for the Hyades group giants, and a chemical homogeneity with the Hyades group giants. A preliminary (Mv, C1)-calibration is briefly discussed. NGC 2482, which may contain the cataclysmic variable BX Pup, is slightly younger than the Hyades and NGC 2323, but the metal abundance is similar.
