OLIVA-MERCADO, G. Andree; BONATTI-GONZALEZ, Javier; CORDERO-GARCIA, Iván  e  FRUTOS-ALFARO, Francisco. A visualization of null geodesics for the bonnor massive dipole. Rev. Mat [online]. 2015, vol.22, n.2, pp.255-264. ISSN 1409-2433.

In this work we simulate null geodesics for the Bonnor massive dipole metric by implementing a symbolic-numerical algorithm in Sage and Python. This program is also capable of visualizing in 3D, in principle, the geodesics for any given metric. Geodesics are launched from a common point, collectively forming a cone of light beams, simulating a solid-angle section of a point source in front of a massive object with a magnetic field. Parallel light beams also were considered, and their bending due to the curvature of the space-time was simulated.
