J/A+A/431/933      Abundances of NGC 7789 evolved stars    (Tautvaisiene+, 2005)

Chemical composition of evolved stars in the open cluster NGC 7789. Tautvaisiene G., Edvardsson B., Puzeras E., Ilyin I. <Astron. Astrophys. 431, 933 (2005)> =2005A&A...431..933T
ADC_Keywords: Clusters, open ; Stars, horizontal branch ; Abundances Keywords: stars: abundances - stars: atmospheres - stars: horizontal-branch - Galaxy: open clusters and associations: individual: NGC 7789 Abstract: High-resolution spectra of six giants and three core-helium-burning "clump" stars in the open cluster NGC 7789 have been obtained with the SOFIN spectrograph on the Nordic Optical Telescope to investigate abundances of up to 20 chemical elements. Abundances of carbon were studied using the C2 Swan (0, 1) band head at 5635.5Å. The wavelength interval 7980-8130Å with strong CN features was analysed in order to determine nitrogen abundances and 12C/13C isotope ratios. The oxygen abundances were determined from the [O I] line at 6300Å. Description: The spectra were obtained at the Nordic Optical Telescope (NOT) with the SOFIN echelle spectrograph in July of 2001.
