Abstract

We observed five central stars of planetary nebulae (CSPN) in the LMC and three in the SMC with FUSE , in the range 905-1187 Å. We performed a model-based analysis of these spectra in conjunction with HST spectra in the UV and optical range to determine stellar and nebular parameters. The signature of hot ( T ≳ 2000 K) circumstellar molecular hydrogen is found in the FUSE spectra of most objects. We also find evidence of X-rays in the wind of SMP LMC 76.
