2. Software

2.1 Collections

Here are some links to collections and other indexes of Linux astronomy software.

• The Linux for Astronomy CDROM
• Scientific Applications on Linux (SAL), Physics and Astronomy
• Linux Applications and Utilities Page, Science and Math
• AstroMake is a utility intended to make installations of some common astronomical packages (in binary form) easy.
• The linuxastro mailing list also contains a list of applications and packages. For more information, see linuxastro.
• Astronomy at sourceforge.net

If the above does not appeal to your needs, these links may help:

• Linux Astronomy Software from the Google Search Engine
• Astronomy Software from the Yahoo Listings

2.2 Planetarium Programs

Here is discussion of programs which run on Linux for use in finding objects, natural and man-made, in the sky.

• XEphem has been the pet project of one of us (Downey) for the past 15-odd years. It has grown to become one of the more capable interactive tools for the computation of astronomical ephemerides.
• XSky is by Terry R. Friedrichsen, terry@venus.sunquest.com. XSky is essentially an interactive sky atlas.
• Skymap is an astronomical mapping program written in Fortran and C for unix workstations by Doug Mink of the Smithsonian Astrophysical Observatory Telescope Data Center.
• Xplns reproduces real starry sky on your display of X Window System.
• Nightfall is an astronomy application for fun, education, and science. It can produce animated views of eclipsing binary stars, calculate synthetic lightcurves and radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system.
• NOVA free Integrated Observational Environment for astronomers.

2.3 Simulators

Programs that classify themselves as simulators.

• Celestia Real-time visual simulation of space for Windows and Unix(Linux)
• OpenUniverse Simulates the Solar System bodies in 3D in Windows and Linux

2.4 Libraries

This section discusses bits and pieces of software that can be used to form the basis for specialized projects.

• SLALIB, part of the Starlink Project, is a complete library of subroutines for astrometric computations.
• Astrophysics Source Code Library is a collection of links to numerical astrophysical process models.
• Astronomy and numerical software source codes is a collection of C codes related to astronomy.
• How to compute planetary positions.
• CCD Astronomy on Linux. A library of routines that help control SBIG cameras.

2.5 Games

Yes, games.

• Orbit - Be a space fighter pilot in Windows or Linux.

2.6 Other

Every list needs a miscellaneous section, and this is it for Software.

• IRAF is a gigantic but exceptionally capable astronomical analysis system, shepherded over the past 20-odd years by Doug Tody of NOAO. It has accumulated innumerable authoritative contributions from leading astronomers in all areas of astronomical data analysis. If you have a serious interest in astronomical data reduction and significant time to invest, this system will reward you mightily.
• Nightfall Eclipsing Binary Star Program
• Xplanet Very realistic rendering program for Earth and other planets and moons. Uses X Windows and OpenGL.
• StarPlot A 3-Dimensional Star Chart Viewer for Linux. Uses C++ and Gtk+.
