Scientific paper

Four more planetary nebulae (PN) in the Magellanic clouds were observed with IUE (LMC P2, P9, P33, and SMC N43). Reliable C abundances were computed for each PN, and other abundances were calculated from ionization models taking the IUE and earlier groundbased spectra into consideration. P9 has the richest spectrum of any extragalactic PN studied in the UV; three ionization stages of N were detected. Three PN (LMC P40, SMC N2, N5) were reobserved to search for time variations that might be anticipated from the relatively high luminosities and masses that were derived for the central stars of these young, compact objects. For P40, with a derived central star mass of 1.2, the continuum observations hint at variation of the anticipated type but are not decisive.
