VizieR Online Data Catalog: Optical spectra of 7 hot UV bright stars in GC (Moehler+, 1998)
Abstract
Optical low-resolution spectra of 7 UV bright stars in globular clusters are presented together with the atmospheric parameters derived from them. The following globular clusters have been observed: NGC2808, NGC6121, NGC6723, NGC6752. The continuum of the spectra has ben normalized and they were resampled to laboratory wavelengths. Effective temperatures, surface gravities, and helium abundances were derived from line profile fits.
