Scientific paper

LB 3459 is an eclipsing, close, post common-envelope binary consisting of a sdOB-type post-EHB primary star (M1 = 0.45Msolar) and a low-mass M dwarf secondary star (M2 = 0.076Msolar). A NLTE spectral analysis of FUSE observations has shown that the rotation of the primary is bound with 35+/-10 km/sec. Phosphorus and sulfur are newly identified in the FUSE observations. The abundances are solar and 0.01 times solar, respectively.
