ChiantiPy is a Python interface to the CHIANTI atomic database for astrophysical spectroscopy. The CHIANTI atomic database for astrophysical spectroscopy provides the information necessary to calculate the emission spectrum from hot plasmas. ChiantiPy provides several top-level classes to access the database and calculate continuum and emission line intensities.

Simulum deals with different simulations of star movements
and their visualizations. At first it looks at the projection and
accumulation of star brightness. In actually doing this it
distributes stars among a three dimensional figure. To get a
nice effect it combines the photographic image production
with a moving view point. So the outcome is the visual
impression of flying through a star field. Secondly it studies
different algorithms of particle movements and clustering.
The primary approach uses a combination of Newton's
gravitational law, energy, and impulse conservation. At all
these stages an highly dynamic view of the processes is able
to be produced.

libnova is a general purpose, double precision, celestial mechanics and astronomical calculation library. It can calculate aberration, nutation, apparent position, dynamical time, Julian day, precession, proper motion, sidereal time, solar coordinates (using VSOP87), coordinate transformations, planetary positions (Mercury - Neptune using VSOP87), planetary magnitude, illuminated disk and phase angle, lunar position (using ELP82), phase angle, elliptic motion of bodies (Asteroid + Comet positional and orbit data), asteroid + comet magnitudes, parabolic motion of bodies (comet positional data), orbit velocities and lengths, atmospheric refraction, rise/set/transit times, and semidiameters of the Sun, Moon, planets, and asteroids.

SImg is a software for astronomical image processing. It contains a tool for visualization of highly dynamic images. The package consists of a library and applications which use it. Some of the features are deconvolution (various methods), Video4Linux support, PSF computation, approximation by linear combination of images and polynoms, various color transforms, automatic shifting of image sets (for addition and color composition), and more.

AstroAviBrowser is a small tool for astronomy imaging capture/processing. It allows you to open a video file, select the good frames, and save the new sequence in a new avi file using raw or lossless codecs. You may also de-bayer your frames and separate RGB plans. It's a kind of "AviRaw" for Linux.

StarPlot is a GTK-based program, written in C++,
which can be used interactively to view
three-dimensional perspective charts of stars.
Charts can be recentered, rotated, or zoomed in or
out with a mouse click (this can also, of course,
be done via dialog boxes for more precision).
Stars may be viewed (or ignored) by spectral class
and absolute magnitude. Other features include
support for both celestial and galactic coordinate
systems, the ability to display extended
non-stellar objects, and a pop-up
Hertzsprung-Russell diagram. StarPlot is also
packaged with starconvert, a utility which
converts line-oriented stellar data records to
StarPlot format. Most star data files available on
the Internet can be converted this way if a short
file describing the original file format is
provided to starconvert.
