A Comparative Study of the Mass Distribution of Extreme-Ultraviolet selected White Dwarfs
(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 ...
Optical spectroscopy of the candidate luminous white dwarf in the young Large Magellanic Cloud cluster NGC 1818
(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, ...
How accurately do we know the parameters of hot DA white dwarfs
(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 ...
Spectral analysis of the binary sdB star Feige 36
(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 ...
