Gravitational lensing effect of static neutron stars with magnetic dipole moment and magnetic charge
摘要
Abstract
This paper investigates the gravitational lensing effect of static neutron stars with magnetic dipole mo-ment and magnetic charge.Using the geodesic equation,the photon light sphere radius in the neutron star space-time has been derived,which decreases as the magnetic charge increases.In the study of the gravitational len-sing deflection angle,It is founded that the deflection angle increases with the magnetic charge,while it decrea-ses with the magnetic dipole moment.When the magnetic charge is 0.5,the deflection angle becomes a con-stant,independent of the magnetic moment.Additionally,when both the magnetic charge and magnetic dipole moment tend to zero,all parameters revert to the Schwarzschild case.The influence of observable lensing quanti-ties on the deflection angle has been further analyzed by using actual observational neutron star data.The results show that the deflection angle increases with the neutron star's mass,the observer's proximity,and the mass-to-distance ratio.These findings provide important insights for studying the properties of neutron stars.关键词
