Red giants abundances in 4 open clusters
Listed in IVOA Registry (Virtual Observatory)
We have analysed high-dispersion echelle spectra (R>~50000) of red giant members for four open clusters to derive abundances for many elements.
Description
The spread in temperatures and gravities being very small among the red giants nearly the same stellar lines were employed thereby reducing the random errors. The errors of average abundance for the cluster were generally in the range 0.02-0.07dex.
Our present sample covers Galactocentric distances of 8.3-10.5kpc. The [Fe/H] values are -0.02+/-0.05 for NGC 752, -0.07+/-0.06 for NGC 2360, -0.11+/-0.05 for NGC 1817 and -0.19+/-0.06 for NGC 2506. Abundances relative to Fe for elements from Na to Eu are equal within measurement uncertainties to published abundances for thin-disc giants in the field.
