Abstract:
The figure-eight solution and slalom solutions are periodic solutions to equal-mass planar three-body problem with vanishing angular momentum. They are called `choreographic` because three bodies chase each other on a single orbit with equal time delay. Slalom solutions are classified by an integer $k$. The $k=5$ slaloms belong to the same homotopy class with five iterations of the figure-eight. Three $k=5$ slalom solutions are known under Newton potential. We continue the figure-eight and slalom solutions to homogeneous potential $1/r^\alpha$. Linear stability and Morse index of them are investigated. Behavior of action integral near bifurcation points are closely examined.
