Central Stars of Planetary Nebulae in the Magellanic Clouds: A Detailed Spectroscopic Analysis
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.
Based on observations made with the NASA-CNES-CSA Far Ultraviolet Spectroscopic Explorer and archival data. FUSE is operated for NASA by the Johns Hopkins University under NASA contract NAS5-32985.- Publication:
