Integrated spectroscopy and individual spectra of stars of open cluster remnants and candidates
The integrated light of open cluster remnants (OCRs) is expected to be similar to that of open clusters of comparable ages. Despite erosion of the mass function in remnants as a consequence of dynamical evolution, their integrated spectra could still be similar to those of the clusters of comparable age as long as a sufficient number of bright stars remain. In the present work we employ integrated spectroscopy and individual spectra of stars to analyze 8 OCRs and candidates which were previously classified as open clusters and a new unclassified object. The OCRs and possible open cluster remnants (POCRs) are underpopulated with respect to usual open clusters, but they show a significant density contrast of bright stars when compared to the Galactic field. The spectroscopic observations were carried out with the 2.15-m telescope at CASLEO (San Juan, Argentina) in the range 3800-6800 Å, during 2003 and 2004. We derive foreground interstellar reddening values and ages. We find in most of the sample that the derived properties are compatible with what should be expected for OCRs.
