Simulate eclipsing binary stars
'Nightfall' simulates eclipsing binary stars and produces animated views, synthetic lightcurves, radial velocity curves, and eventually determine the best-fit model for a given set of observational data of an eclipsing binary star system. It takes into account the non-spherical shape of close binary stars, mutual reflection, and some other effects. It comes with documentation, on-line help, and observational data of real binary stars. The program supports but does not require the Gnome desktop. 'Nightfall' can handle the following configurations: overcontact (common envelope) systems, eccentric (non-circular) orbits, surface spots and asynchroneous rotation (stars rotating slower or faster than the orbital period), and the possible existence of a third star in the system ('third light').
