NLTE Models with Elements H - Ni

In the framework of the Virtual Observatory, the GAVO project provides theoretical spectral energy distributions (SEDs) of TMAP NLTE model atmospheres within the GAVO TheoSSA service. All SEDs from this model-atmosphere grid are available in a VO-compliant form within TheoSSA.

In contrast to the H-Ca grid, Ca is treated like the iron-group elements, i.e. we consider all its spectral lines given by Kurucz. The elements Ca - Ni are represented by a generic model atom.



The impact of metal-line blanketing due to (Ca + iron-group) elements is demonstrated in this figure. The stellar flux has definitely nothing to do with a black body. Click on the above image to see some details.

Note: The following tables are not suitable for precise spectral analyses
because only approximate formulae were used in order to account for Stark line broadening.

NLTE model atmosphere fluxes (5 - 2000Å)
calculated for the use with the photoionization code CLOUDY.
The flux is binned to 0.1Å intervals.
[ ]: log (abundance / solar abundance)
In all files the effective temperature calculated from the integrated flux is given. The flux may be normalized to the correct effective temperature.
