Photometric observations and Coravel radial velocities of red giant candidates in open clusters
Abstract
We present high precision multicolour photoelectric photometry together with Coravel radial-velocity data for a sample of red giant (RG) candidates in nine Galactic open clusters. Nearly 82% of the analyzed stars are found to be cluster RGs from photometric criteria, in excellent agreement with Coravel membership probabilities. E(B-V) colour excesses, effective temperatures and metallicities are derived for the cluster giants. A new spectroscopic binary was discovered among the RGs of NGC 2482.
