Abundances in planetary nebulae: NGC6826.

SURENDIRANATH R. and POTTASCH S.R.

Abstract (from CDS):

We determine the chemical abundances and other parameters of the nebula NGC6826 and its central star. We present new ISO spectra and combine them with archival IUE and optical spectra from the literature to get a complete, extinction-corrected, spectrum. The chemical composition of the nebula is then calculated in two ways, first by directly calculating and adding individual ion abundances, and second by building a model nebula that will reproduce the observed spectrum. The results of these two methods are compared. In addition, we discuss the star exciting the nebula.
