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.

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 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.

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 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. |

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. |

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. |

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. |

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. |
