THE ROLE OF HeH IN COOL HELIUM-RICH WHITE DWARFS
HeH is found to be the dominant positive ion over a wide range of temperatures and densities relevant to helium-rich white dwarfs. The inclusion of HeH in ionization equilibrium computations increases the abundance of free electrons by a significant factor. For temperatures below 8000 K, He free-free absorption is increased by up to a factor of 5 by the inclusion of HeH . Illustrative model atm...
متن کاملCool helium-rich white dwarfs from the Hamburg/ESO survey
We present an analysis of 40 cool helium-rich white dwarfs found in the Hamburg/ESO survey. They were selected for follow-up spectroscopy because of their U −B colour below -0.18, the absence of strong absorption lines, and a continuum shape similar to that of a quasar. Effective temperatures for individual stars were determined by fitting model atmospheres of nearly pure helium with a small ad...
متن کاملThe First Mid-Infrared Spectra of Cool White Dwarfs
We present the first mid-infrared spectra of two cool white dwarfs obtained with the Spitzer Space Telescope. We also present 3:5Y8 m photometry for 19 cool white dwarfs with 5000 K TeA 9000 K. We perform a detailed model atmosphere analysis of these white dwarfs by fitting their UBVRIJHK and Spitzer photometry with state-ofthe-art model atmospheres, and demonstrate that the optical and infrare...
متن کاملThe Ages of Very Cool Hydrogen–rich White Dwarfs
The evolution of white dwarfs is essentially a cooling process that depends primarily on the energy stored in their degenerate cores and on the transparency of their envelopes. In this paper we compute accurate cooling sequences for carbon–oxygen white dwarfs with hydrogen dominated atmospheres for the full range of masses of interest. For this purpose we use the most accurate available physica...
متن کاملThe Rotational Velocity of Helium-rich Pre-White Dwarfs
Previous investigations on hydrogen-rich white dwarfs generally yield only very small rotational velocities (vrot · sin i). We have analyzed line profiles in high-resolution optical spectra of eight hydrogen-deficient (pre-) white dwarfs and find deviations from the dominant Stark line broadening in five cases which, interpreted as an effect of stellar rotation, indicate projected rotational ve...
