Description
English: Gravitational lensing of the image of a massless companion star (red) by a neutron star (blue).

The companion star is sitting behind the neutron star. Its image is distorted by the gravitational lensing of light. The geometry and the colors of the depicted scene is astrophysically unrealistic (in the vicinity of a neutron star, a companion star would be not stable). They were chosen so that the influence of gravitational lensing would be clearly visible.

Mass of the neutron star: 1, radius of the neutron star: 4, radius of the companion star: 8, orbital radius: 20, all numbers in dimensionless units.
Deutsch: Umlauf eines masselosen Begleitsterns (rot) um einen Neutronenstern (blau). Der Begleitstern befindet sich schräg hinter dem Neutronenstern. Sein Anblick wird durch die gravitative Lichtablenkung verzerrt.

Die Geometrie und Farbgebung der dargestellten Szene ist astrophysikalisch völlig unrealistisch (in dieser Nähe eines Neutronensterns wäre ein Begleiter nicht stabil). Sie wurde so gewählt, dass der Einfluss der gravitativen Lichtablenkung deutlich zu sehen ist.

Masse des Neutronensterns: 1, Radius des Neutronensterns: 4, Radius des Begleitsterns: 8, Bahnradius: 20, alle Zahlenwerte in dimensionslosen Einheiten.
