Inhomogeneous potentials producing homogeneous orbits
Abstract We prove that, in general, a given two-dimensional inhomogeneous potential \(V(x,y)\) does not allow for the creation of homogeneous…

Symmetries in the Popovici-Manev photogravitational field
Abstract The Popovici-Manev photogravitational field is generated by a Manev-type attraction force and the repelling radiative force considered by Constantin…
Persistence of planetary rings under the influence of the anisotropically re-emitted solar radiation
Abstract The solar radiation has a destabilizing influence on planetary rings. The shepherding satellites explain the persistence of these structures,…
Families of orbits in conservative fields of Hénon-Heiles type
