A near-IR spectroscopic search for very-low-mass cool companions to notable DA white dwarfs
P. D. Dobbie, M. R. Burleigh, A. J. Levan +5
We have undertaken a detailed near-IR spectroscopic analysis of eight notable white dwarfs, predominantly of southern declination. In each case the spectrum failed to reveal compel…
Metal Abundances in Hot DA White Dwarfs
S. Schuh, M. A. Barstow, S. Dreizler
We compare measured element abundances in hot DA white dwarfs from UV observations to predictions from our self-consistent non-LTE model atmosphere diffusion calculations.
Whole Earth Telescope observations of BPM 37093: a seismological test of crystallization theory in white dwarfs
A. Kanaan, A. Nitta, D. E. Winget +3
BPM 37093 is the only hydrogen-atmosphere white dwarf currently known which has sufficient mass (~ 1.1 M_sun) to theoretically crystallize while still inside the ZZ Ceti instabilit…
RX J2130.6+4710 - an eclipsing white dwarf - M-dwarf binary star
P. F. L. Maxted, T. R. Marsh, L. Morales-Rueda +5
(Abridged) We report the detection of eclipses in the close white-dwarf - M-dwarf binary star RXJ2130.6+4710. We estimate that the spectral type of the M-dwarf is M3.5Ve or M4Ve. W…
Chandra and FUSE spectroscopy of the hot bare stellar core H1504+65
K. Werner, T. Rauch, M. A. Barstow +1
H1504+65 is an extremely hot hydrogen-deficient white dwarf with an effective temperature close to 200,000 K. We present new FUV and soft X-ray spectra obtained with FUSE and Chand…
