A Comparative Study of the Mass Distribution of Extreme-Ultraviolet selected White Dwarfs
Napiwotzki, R.; Green, P.J.; Saffer, R. (1999)We present new determinations of e ective temperature, surface gravity, and masses for a sample of 46 hot DA white dwarfs selected from the Extreme Ultraviolet Explorer (EUV E) and ROSAT Wide Field Camera bright source ... -
How accurately do we know the parameters of hot DA white dwarfs
Napiwotzki, R.; Green, P.J.; Saffer, R. (Astronomical Society of the Pacific, 1999)We present new determinations of effective temperature, surface gravity, and masses for a sample of hot DA white dwarfs selected from the EUVE and ROSAT Wide Field Camera bright source lists in the course of a near-IR ... -
Optical spectroscopy of the candidate luminous white dwarf in the young Large Magellanic Cloud cluster NGC 1818
Burleigh, M.R.; Saffer, R.; Gilmore, G.F.; Napiwotzki, R. (1999)An optical spectrum of the Elson et al. (1998) candidate luminous white dwarf in the young LMC cluster NGC1818 shows conclusively that it is not a degenerate star. A model atmosphere fit gives Teff 31,500K and log g 4.4, ... -
Spectral analysis of the binary sdB star Feige 36
Edelmann, H.; Heber, U.; Napiwotzki, R.; Reid, I.N.; Saffer, R. (Astronomical Society of the Pacific, 1999)The sdB stars Feige 36 is a short-period, single-lined spectroscopic binary. Aymospheric parameters and abundances are determined from high-resolution Keck spectra. Feige 36 lies near the zero-age extreme Horizontal Branch ... -
