CCD Photometry of NGC 2482 and Five Previously Unobserved Open Star Clusters Academic Article uri icon


  • 2015. The Astronomical Society of the Pacific. All rights reserved. We present BV and u0g0r0i0 CCD photometry of the central region of NGC 2482. We also present BV u0g0 CCD photometry of five clusters that have been poorly studied in the past: Ruprecht 42, Ruprecht 51, Ruprecht 153, Ruprecht 154, and AH03 J0748-26.9, which to our knowledge has not been studied before. Using a global optimization technique that eliminates much of the subjectivity previously inherent in main-sequence fitting studies, we obtain values of the distances, ages, and metallicities of the clusters, with robust estimates of the uncertainties of these fundamental parameters. Four of our clusters are less than 1:3 kpc beyond the Suns distance from the Galactic center and have essentially solar metallicity. The metallicities of those clusters more distant from the Galactic center are consistent with a 0.3 dex step to lower [Fe/H] found in other studies
