I was one of the boring stellar astronomers who plays AC/DC with his guitar
plugged into the home built 500 Watt amplifyer, listens Commodore-64 music
at home and models stellar atmospheres.
The amplifyers are smaller now, but the guitars got more.

Codes I did in the past or I am still working on, like Flux Conversion,
the Little Spectrum Analyser, and various stellar atmosphere modelling and
abundance analysis tools, can still be found on the
Software page.

Concerning a degree as doctor in natural sciences, I did write a code that
combines the reynold stress model approach for modelling convection in stars,
treatment of individual and depth dependent elemental abundances in stellar
atmospheres and also the contribution of molecules to the radiative equilibrium.
The work, VeDyn, is published (Stütz Ch., 2009, A&A 505, 1233).
However, I am quite displeased with the way science is promoted and funded
these days. So I changed from professional to hobby scientist.

My master theses at the Institute for Astronomy of Vienna, the Delta-a
(Da) Catalog contains most measurements in the Da-photometric-filter-system
obtained in the years 1976 - 2000. The stars range from spectral type F4 to B2.
Although the Da-system was created to detect CP2 (Preston 1974) stars, also the
other types of chemicaly peculiar "A" stars such as Am, HgMn, He-wk, He-str or
LambdaBoo are present. Overall the Catalog consists of somewhat around 2500
stars, where 1500 were observed in the field and about 1000 belong to star
clusters. At present the Da Catalog is available at the University of Vienna
and the Institute for Astronomy at the University of Vienna in german language.
An english version will be published. You can download the catalog
(Stütz, 2000) as number-symbol separated values (nsv) file and
a file description below.
