Abstract. AA Dor is an eclipsing, close, post common-envelope binary (PCEB) consisting of a sdOB primary star and an unseen secondary with an extraordinary small mass - formally a brown dwarf. We present results of NLTE spectral analysis based on phase-dependent high-resolution UVES spectroscopy.
Key words: Stars: binaries: eclipsing, Stars: common envelope, Stars: evolution, Stars: individual: AA Dor, Stars: low-mass, brown dwarfs
