15 صفحه اولMetallicity of the young halo globular cluster Ruprecht 106 ?
Medium resolution spectra of 3 stars have been used to determine the metallicity of the globular cluster Ruprecht 106. On the basis of a code developed by Cayrel et al. (1991), we computed a grid of synthetic spectra in order to derive the metallicity of these stars. We found an abundance of [F e/H] = −1.6 ± 0.25 which, although not formally at variance with the estimate of metallicity based on...

Context. We continue our survey for magnetic chemically peculiar (CP2) stars in galactic open clusters to shed more light on their origin and evolution. Aims. To study the group of CP2 stars, it is essential to find these objects in different galactic environments and at a wide range of evolutionary stages. The knowledge of open clusters ages and metallicities can help to find a correlation of ...
