| dc.description | AA Dor (LB 3459) is an eclipsing, close, single-lined, post common-envelope binary (PCEB) consisting of an sdOB primary star and an unseen secondary with an extraordinary small mass - formally a brown dwarf. The brown dwarf may have been a former planet which survived a common envelope phase and has even gained mass. A recent determination of the components' masses from results of state-of-the-art NLTE spectral analysis and subsequent comparison to evolutionary tracks shows a discrepancy between masses derived from radial-velocity and the eclipse curves. Phase-resolved high-resolution and high-SN spectroscopy was carried out with FUSE in order to investigate on this problem. We present preliminary results of an ongoing NLTE spectral analysis of FUSE spectra of the primary. | |
