Description

Pulsars are rapidly rotating, highly magnetized neutron stars that emit periodic pulses of radiation across a broad range of wavelengths, from radio to gamma rays. Despite decades of study, the mechanisms responsible for their radiation remain unclear. In this work, we investigate the correlations between the radio emission of X-ray–emitting pulsars and their X-ray properties. We find that the radio luminosity of these pulsars exhibits a non-monotonic relationship with their surface temperatures, forming a hump-shaped distribution. Specifically, pulsars in the lower-temperature regime show a positive correlation, whereas those with higher surface temperatures exhibit a distinctly different trend. This phenomenological distribution suggests a possible transition or two different regimes in the production of electron-positron pairs responsible for radio emissions.
