A grid of non-LTE model atmospheres for white dwarfs in cataclysmic variables

We have calculated a grid of non-LTE (NLTE) line-blanketed model atmosphere s for white dwarfs in cataclysmic variable (CV) systems using our stellar a tmosphere code PHOENIX. The grid covers the temperature range 20,000-500,00 0 K for solar abundances and 10(-2) and 10(-4) solar metal abundance. The e ffective temperature resolution is 10,000 K in the range 20,000-200,000 K a nd is 20,000 K in the range 200,00-500,000 K. The models include a large nu mber of NLTE levels for light metals such as CNO and heavy metals such as N i and Fe. The necessity of using self-consistent NLTE line-blanketed model atmospheres for the analysis of white dwarfs is well known and reaffirmed h ere. We discuss the importance of metal opacity, especially metals heavier than Ca, in the atmospheres of CV primaries. We also compare our grid to pr eviously published models and discuss the general improvements offered by o ur models. In addition, a specific model from our grid is compared to a Hub ble Space Telescope observation of U Gem and predictions for Far-Ultraviole t Spectroscopic Explorer (FUSE) observations are made.
