Astronomy Observation Planning Software
Tara is a (hopefully) elegant and concise N-body integrator written in Ruby with C extensions.
The IRAF64 Project is porting the IRAF software to the X86_64 Linux OS with NATIVE X86_64(Opteron,EM64T) executable.
This project is an initial reference implementation of the VSI-E protocol. The implementation has been done using the C/C++ language and is in the form of a re-useable library developed on the Linux platform.
Chimera is a system to automates astronomical observatory tasks.
Electronic computational sky atlas
Library for spherical harmonic transforms (SHT)
Calculate Solunar Tables for any position on earth. Solunar tables are used to predict the best days and times of day to go hunting and fishing.
A Calendar Conversion Program for Gregorian Solar Calendar and Chinese Lunar Calendar
The motivation for this project came from the fact that there is no OSS Platform Independent Astro App available for all forms of Astrology.My current scope is Vedic astrology in Krishnamurti Paddhati and that too in English extend able to other forms.
A gravity simulator using rutta kunge and octrees to be able to simulate thousands of bodies using the universal law of gravitation. Also has simulation for the solar system with a menu and game.
psrevolve is a parallel MPI code that creates a population of pulsars and tracks their evolution in the galaxy, determining whether they are detectable by large pulsar surveys. A serial (non-parallel) component module is also available.
PWC driver modded for Long Exposure and Led control support
StarBox is a completely free and open source 3d "galaxy" engine. Its purpose is to render huge galaxies and planets but still maintain speed and compability. It uses OpenGL to render, but DirectX support is considerd for Windows systems.
A program for the resampling (warping) and coaddition of astronomical images. Includes the Richardson-Lucy method.
