Contribution
Introduction of the TMAP code for detailed, metal-line blanketed white dwarf atmospheres and its application to super soft sources and hot white dwarf stages.
Findings
TMAP provides high-quality synthetic spectra for hot white dwarfs.
Spectral energy distributions are accessible via GAVO/TheoSSA.
Models are applicable to novae and super soft source analysis.
Abstract
The T\"ubingen NLTE Model-Atmosphere Package (TMAP) calculates fully metal-line blanketed white dwarf model atmospheres and spectral energy distributions (SEDs) at a high level of sophistication. Such SEDs are easily accessible via the German Astrophysical Virtual Observatory (GAVO) service TheoSSA. We discuss applications of TMAP models to (pre) white dwarfs during the hottest stages of their stellar evolution, e.g. in the parameter range of novae and super soft sources.
