Chemical abundances of symbiotic nebulae. II.

COSTA R.D.D. and DE FREITAS PACHECO J.A.

Abstract (from CDS):

We performed optical spectroscopy and chemical abundance analysis for five symbiotic systems: He2-106, He2-127, He2-171, H1-36, and SS122. The calculated He abundances and elemental ratios are consistent with the scenario of symbiotics being wide binary systems where the wind from a cool giant is ionized by a hot source.
