X-ray emission spectrum for axion-photon conversion in magnetospheres of strongly magnetized neutron stars

Understand

Detecting axionic dark matter (DM) could be possible in an X-ray spectrum from strongly magnetized neutron stars (NSs).

• We examine the possibility of axion-photon conversion in the magnetospheres of strongly magnetized NSs.
• In the current work, we investigate how the modified Tolman Oppenheimer Volkoff (TOV) system of equations (in the presence of a magnetic field) affects the energy spectrum of axions and axions-converted-photon flux.
• We have considered the distance-dependent magnetic field in the modified TOV system of equations.
