J/AZh/72/855        Abundances in eta Psc               (Antipova+, 1995)

On the chemical composition of the G7 IIIa red giant eta Piscium. Antipova L.I., Berdyugina S.V., Savanov I.S. <Astron. Zh. 72, 855 (1995)> =1995AZh....72..855A =1995ARep...39..761A
ADC_Keywords: Stars, G-type ; Spectroscopy ; Abundances Abstract: CCD observations are used to analyse the atmosphere of the G7 IIIa giant Eta Piscium. The following atmospheric parameters were obtained: T(eff)=4930K, logg=2.1, and microturbulence v(t)=1.7km/s. The abundances of 21 elements in the atmosphere of eta Psc were determined.
