The Hdef grids of
synthetic stellar-atmosphere spectra of Keller et al. 2011 comprise far-UV, optical,
and IR spectral
regions and are suitable for the analysis of H-deficient CSPNe of
the
[WC]-type hotter than 50kK and PG1159 stars. The grids were calculated with CMFGEN (Hillier
and Miller 1998), a state of the art stellar-atmosphere code that
properly treats the stellar winds, accounting for expanding atmospheres
in non-LTE, line blanketing, and wind clumping. We include in the grids
many ionic species that were previously neglected. They comprise a
uniform set of models that fill a niche in an important parameter
regime, i.e., high effective temperatures, high surface gravities, and
a range of mass loss values and are available for download in this
website through the links above.
