Please specify
effective temperature Teff,
surface gravity log g,
abundances for H, He, C, N, O, Ne, Na, and Mg
as well as your e-mail address.

A NLTE model atmosphere with your input parameters will be calculated by TMAP - the Tübingen NLTE Model-Atmosphere Package - and you will be informed about the progress by e-mail.

SED Parameters

Wavelength range for standard SED:

5 - 2000 Å 2000 - 3000 Å 3000 - 55000 Å

Wavelength range for an individual SED and a quicklook plot:

- Å, Δλ ≈ Å

Note: the maximum number of data points is about 50 000.


Before submitting, please verify the entered data, especially your e-mail address.

Model-Grid Parameters

Teff / K: 20 kK ≤ Teff ≤ 300 kK
Teff / K (pure H+He): 20 kK ≤ Teff ≤ 1 MK
Minimum Maximum Grid spacing
log (g / cm/s2): 4.0 ≤ log g ≤ 9.9
Minimum Maximum Grid spacing

Abundances [mass fractions, preset with solar values (Asplund et al., 2009, Scott et al., 2015)]:

H He
Ne Na Mg

Presently, only SEDs of hot, compact stars can be calculated.
To exclude elements from the calculation, just set their abundance to 0.0.
The calculation of a H+He+C+N+O SED takes about one or two days, a H+He+C+N+O+Ne+Na+Mg SED calculation takes up to five days.
Numerical instabilities may occur due to the requested parameters. We will then check for these asap.

Please do not hesitate to start any calculation - this helps us to further improve the TMAW procedure.

Manuals how to use TheoSSA and TMAW are available (in PDF format) in english and german.

The interaction of the GAVO services TheoSSA and TMAW is demonstrated in case of the central star of the planetary nebula PRTM 1 here. .

Please do not hesitate to should any question arise.
