GRorbits

Relativistic Orbits of Matter and Light in the Equatorial Plane of a Schwarzschild Black Hole

INSTRUCTIONS

This Java software allows you to view and manipulate orbits predicted by Newtonian mechanics and by general relativity. The menu items at the top of the display and the buttons at the bottom are self-explanatory. (For an explanation of rain coordinates, see Exploring Black Holes, page B-4 and the following pages.)

NOTE: Setting the angular momentum limits the available energies; setting both angular momentum and energy limits the initial radii.
