SolSyIn (Solar System Integrator)
package is a collection of programs for manipulating dynamical systems
of bodies (especially related to our Solar System). Firstly, it is a numerical
integrator for a system of bodies (up to 10,000) moving in gravitational
(newtonian/relativistic) and radiative field, using Radau-Everhart 15th
order algorithm which is optimized for accurately handling close encounters.
It is also a graphic displayer of the integrated systems, a checker of
accuracy and data browser, a system maker in various configurations (including
real bodies taken from professional catalogs), a table maker with various
orbital quantities (rectangular coordinates, keplerian and equinoctial
orbital elements, mutual distances between bodies and orbits, resonance's
arguments, coordinates in target plane, etc) and, finally, a plotter of
all these parameters in 2D and 3D graphs (with the help of GnuPlot library).
It can be used in research activities but also as an educational tool.
Comprehensive information can be found in the online manual. There are also listed some useful links and information about various catalogs that SolSyIn can understand and use. Several examples are given, for illustrating some SolSyIn capabilities. In the download section you will find the standard distribution of the package and auxiliary catalogs. A postscript version of the manuals (both English and Romanian) is also available, Any comments and suggestions are welcomed!
