Scientific paper

High resolution IUE spectra of the low excitation nebula BD +30°3639 show absorption lines of nebular material and of the intervening ISM. With the method described in Pwa et al. (1984) ionic abundances were derived for Mg0, Mn+, Fe+, Zn+ (all for the first time in a PN) and for Mg+, Al+, Al2+, Si+, O0. Using ratios of collisionally excited emission lines in the UV and of available optical and IR data abundances of some ions were (re)derived or upper limits deduced. It has been found: C = 8.6, O = 8.4, Mg = 6.6, Al = 5.4, Si = 6.3, S = 6.8, Mn ≥ 4.7, Fe ≥ 6.3, Zn ≥ 5.0. The authors also estimate the possible dust mass assuming that the depletion of the refractory elements has been caused by their forming grains.
