Nightfall

Astronomy for fun (education, science, whatever). Nightfall is an interactive application to simulate eclipsing binary stars, and to produce animated views, synthetic lightcurves and more. Takes into account the non-spherical shape of close binary stars, mutual reflection, and some other effects. Comes with documentation, on-line help, and lots of observational data of real binary stars. Supports the Gnome desktop, but doesn't require it.

          Release Notes: This release fixes some bugs in the star-disk eclipse verification.

          •  12 Apr 2007 14:52

            Release Notes: This release adds the option to model an accretion disk. Minor numerical bugs have been fixed, and the "sqrt individual" limb darkening option has been removed, since it has no proper flux normalization, and hence yields incorrect results.
