Abstract In the last decade, X‐ray observations of hot stellar objects became available with unprecedented resolution and S/N ratio. For an adequate interpretation, fully metal‐line blanketed Non‐LTE model‐atmospheres are necessary. The Tübingen Non‐LTE Model Atmosphere Package (TMAP) can calculate such model atmospheres at a high level of sophistication. Although TMAP is not especially designed for the calculation of spectral energy distributions (SEDs) at extreme photospheric parameters, it can be employed for the spectral analysis ofburst spectra of novae like V4743 Sgr or line identifications in observations of neutron stars with low magnetic fields in low‐mass X‐ray binaries (LMXBs) like EXO 0748‐676 (© 2010 WILEY‐VCH Verlag GmbH & Co.
