Investigation of the II-90 giant in globular cluster M 13.
KLOCHKOVA V.G., MISHENINA T.V. and PANCHUK V.E.
Abstract (from CDS):
A model-atmopshere analysis of the II-90 giant in the globular cluster M 13 is made on high-dispersion spectra taken with the echelle-spectrometer at the 6-m telescope of the Special Astrophysical Observatory. The abundances of 23 chemical elements are determined. The excess of sodium, aluminium, silicon and titanium is found relative to iron-peak elements. The overabundance of elements (La, Pr, Nd, Eu) synthesized mainly in reaction with high-density neutron flux is detected. The oxygen abundance is [O/Fe]=0.07. Estimates are made of the lithium abundance.
