Use the SOS applet to study the types of orbits found
in a logarithmic potential.
- Start with the singular logarithmic potential. Use an axisymmetric
potential.
- characterize the kinds of orbits you find (loop orbits? box orbits? boxlets?).
- use progressively more flattened potentials. How do the orbits change?
- for a given shape, look at the orbit structure at different energies.
How do the orbits change as you change energy?
- Now look at the logarithmic potential with a core.
- characterize the orbit content of the model as you go from a round to a flattened potential.
- characterize how the orbit content changes as you change energy.
- Look at the logarithmic potential with a core and an axis
ratio of 0.7.
- What is the orbit content of this model.
- Now turn on the black hole. How do the orbits change? Why do the orbits change? What does this
mean for the evolution of such a galaxy with a black hole?
