Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments.

A Bayesian analysis of neutron star mass and radius observations based on O2scl.

This is a set of spectral models for use in the astronomical X-ray spectral modeling program XSPEC. The models calculate X-ray emission line Doppler profiles from the winds of OB stars.

Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. ...

Mizar is an N-body gravitational simulator. Given a starting setup consisting of the masses, positions, and velocities of any number of objects (conceptually, planets and stars), Mizar calculates and draws how they subsequently move according to their velocities and the influence of each other's gravity. Requirements: * KDE 4.4.5 * Qt 4.6.2 Requirements to build: * KDE 4.4.5 dev files (e.g., provided by kdelibs5-dev in Ubuntu 10.04) * Qt 4.6.2 dev files (e.g., libqt4-dev on Ubuntu 10.04) * libgsl (e.g., libgsl0-dev on Ubuntu 10.04) * cmake * gcc, g++ 4.4.3 * python 2.6

BeamFlow is a scientific presentation and demonstration program for typical introductory physics problems involving electric, magnetic, and gravity fields in three dimensions. Real-time demonstration of the magnetic field around a wire, the gravity fields around rotating binary stars, and the electric field from multiple point charges are just some of the potential applications.

ephemeritis is to be a library for ephemeris calculations. When complete, it will provide an API for calculating the positions, the rise and set times, and related information about stars, planets, the Moon, and other astronomical objects.

A universe simulator and generator written in Java that is capable of simulating stars with planetary systems, binary systems and other phenomena. This universe can be generated or scripted (in small parts). This will be used in a planned space combat/

A framework for generating a random universe populated with random stars, planets, etc. Uses the laws of physics and the known periodic table of elements for computations.
