J/AZh/72/864        Abundances in gamma Sge                (Boyarchuk+, 1995)

Elemental abundances in the atmosphere of the red giant gamma Sagittae. Boyarchuk A.A., Antipova L.I., Boyarchuk M.E., Savanov I.S. <Astron. Zh. 72, 864 (1995)> =1995AZh....72..864B =1995ARep...39..770B
ADC_Keywords: Stars, M-type ; Spectroscopy ; Abundances Abstract: CCD spectra are used to analyse the abundances of chemical elements in the atmosphere of the MOIII giant gamma Sagittae. Its atmospheric atmospheric parameters were determined to be T(eff)=3970K, logg=1.3, and microturbulence v(t)=1.65km/s.
