WebMay 5, 2024 · Spherical cap: For the case where the water only comes into contact with one of the planes, since the surface is connected and axisymmetric, we obtain a spherical cap as the minimizer by applying Theorem 1. The size and shape of the sphere are decided from the volume constraint and the Duprè–Young condition. Web1.7. ORBITS IN AXISYMMETRIC POTENTIALS 23 1.7 Orbits in axisymmetric potentials We have seen above that empirically, most galaxies are not spherically symmetric, but rather have flattened disks or ellipsoidal shapes. For many of these more general potentials, azimuthal symmetry and also up-down symmetry (z −z) are still fine approximations.
