Higher multipoles of the cow
- View PDF HTML (experimental) Abstract:The spherical cow approximation is widely used in the literature, but is rarely justified.
- Here, I propose several schemes for extending the spherical cow approximation to a full multipole expansion, in which the spherical cow is simply the first term.
- This allows for the computation of bovine potentials and interactions beyond spherical symmetry, and also provides a scheme for defining the geometry of the cow itself at higher multipole moments.
