VERY good free Software: XEphem (Linux - Solaris - OS X - FreeBSD: I have all the catalogs!) Cartes du Ciel - Sky Charts (Windows, Linux version in alpha version)NBODY:This is a collection of programs
for gravitational simulation of the n-body problem
(i.e., gravitational evolution of n point masses under given initial conditions),
and the central (restricted) (n+N)-body problem.
I made them in C++ with a TCL graphical interface, so they work
under Unix and Linux.
Here you have a
precompiled RPM binary (RedHat Linux 9.0). Please contact me if you want the source codes.
