Astronomical Tools Collection


On this page you find a collection of software tools and packages for the use in stellar astronomy. The codes have been developed around the AMS - SAPS team at the Institute for Astronomy at the University of Vienna. Altough the software collected here shows a status from 2000 to 2009, you might be interrested in some of the packages. If you are, simply write an e-mail to the programmers. The contact addresses are stated below every short descripion. ATC


LLmodels80
(s) STARSP goup
Release 8.0 of the LLmodels code. Compiles under Linux, Mac OSX and Windows.
Coding: Fortran 90

LLmodelsSE Shulyak D., Tsymbal V., Ryabchikova T., Stütz Ch., Weiss, W.W., 2004, A&A 428, 993
The model atmosphere code LLmodelsSE allows to calculate 1D plan-parallel, LTE atmospheric models for F to B stars near the main sequence. Line absorbtion can be calculated directly for each line in a preselected line list, making allowance for individual abundance patterns, element stratification and depth dependent microturbulence, or via opacity function, which does not support the last two features. For treatment of convection there is the choice between the local full spectrum turbulence model by Canuto and Mazzitelli 1991 and mixing length theory.

Synth.v3 Kochukhov, O.: Spectrum synthesis for magnetic, chemically stratified stellar atmospheres, 2006, in Physics of Magnetic Stars, eds. I.I. Romanyuk and D. O. Kudryavtsev, 109 (astro-ph / 0701084)
Synth.v3 is a non-magnetic spectrum synthesis code. It works with model atmospheres in Kurucz format and VALD Sf line lists. It features element stratification, molecular equilibrium and individual microturbulence for each line. Disk integration can be done with s3di which is included in the archive.
Coding: Fortran 77/90

Synthmag Kochukhov, O.: Spectrum synthesis for magnetic, chemically stratified stellar atmospheres, 2006, in Physics of Magnetic Stars, eds. I.I. Romanyuk and D. O. Kudryavtsev, 109 (astro-ph / 0701084)
Synthmag-fast solves the RT equations for all 4 Stokes parameters for a given constant magnetic field configuration. As Synth3 it works with model atmospheres in Kurucz format, but post processed (Zeeman v.1.21) VALD Lf line lists. Disk integration again can be done with s3di which is included in the archive.

SynthV Tsymbal, V.V., 1996, in Model Atmospheres and SpectralSynthesis, ed. S.J.Adelman, F.Kupka & W.W.Weiss, ASP Conf. Ser., vol. 108, 198
SynthV is a non-magnetic spectrum synthesis code. Individual abundances, dependence of microturbulent velocity with depth and dependence of radial velocity with depth are supported. Kurucz model atmospheres and *.lns format linelists are needed.
Coding: Fortran 90

s3di
Disk integration for Synth3 type synthesis output. Incorporates amomg other the IDL routines rdmag and rtint of Valenti & Anderson.
Coding: Fortran 90

Lispan Stütz, Ch., Bagnulo, S., et al., 2006, A&A 451, 285
Lispan is a little spectrum analyzing tool meant as a helper for abundance analysis. Up to now it features measuring equvalent widths, comparing two synthetic spectra or observations to a synthesis, applying Doppler corrections and some file format conversions.
Coding: Fortran 90
Details: Longstone City

Christian Stütz: christian.stuetz@univie.ac.at

Zeeman v.1.21
Converts long format files from VALD to the SynthMag format. Zeemanpattern computes shifts and relative intensities of the splitted components. The relative intensities are then normalized to 1.
Coding: Fortran 90

Select v3.1 N.E.Piskunov, F.Kupka, T.A.Ryabchikova, W.W.Weiss & C.S.Jeffery, 1995, A&AS, v.112, p.525
Selects atomic lines from a given sample according to atmospheric structure, chemical composition and a selection criterion. It solves the RT equation for the central wavelength of each line, ignoring blends and checks if the central line depth exceeds the specified criterium. This code was written explicitly for the VALD mirror site hosts.

ATC graphical interface Stütz, Ch., Bagnulo, S., et al., 2006, A&A 451, 285
The Atmospheric Tools Compilation are several model and synthese codes, well documented and combined under a tcl/tk user interface. The interface additionally contains several editors for files typically used when calculating models or synthesis with this software, as well as an line-core-fitting routine for abundance analysis. Currently ATC supports LLmodels, synth3, synthmag, select3, zeeman and lispan. The latest developer version also supports LLmodels8.0 and Synthmag_dda.
Coding: Tcl/Tk
