Description
We present a detailed study of the spider binary system PSR J1748-2446A in the globular cluster Terzan 5, utilizing high-resolution radio observations from the MeerTime project on the MeerKAT telescope. In this unique system, a millisecond pulsar (MSP) is in a tight orbit with a low-mass companion star, resulting in complex interactions and eclipsing phenomena. Notably, the pulsar’s intense radiation and wind strip material from the companion, leading to the formation of an outflow that acts as a plasma lens, magnifying the pulsar’s radio emissions during eclipses. Our observations capture this lensing effect, providing an opportunity to investigate the pulse characteristics and polarization properties of the MSP with enhanced precision. We document significant profile changes, time of arrival variations, and fluctuations in brightness during the lensing events.
