Using the high resolution Ultraviolet and Visual Echelle Spectrograph (UVES) mounted on the Very Large Telescope in combination with photometry from the high-speed CCD camera ULTRACAM, we derive precise system parameters for the pre-cataclysmic binary NN Ser. A model fit to the ULTRACAM light curves gives the orbital inclination as i = 89 degrees.6 +/- 0 degrees.2 and the scaled radii, R-WD/a and R-sec/a. Analysis of the He (II) 4686 angstrom absorption line gives a radial velocity amplitude… Expand
