A MeerKAT view of the double pulsar eclipses. Geodetic precession of pulsar B and system geometryPSR J0737−3039A/B is a unique double neutron star binary system in which both neutron stars are detected as radio pulsars. In addition, the system is viewed almost edge on (90.5 deg), allowing us to study the interaction of a radio signal with the neutron star magnetosphere. A variety of general relativity tests could be carried out on this system. In this paper, Lower and collaborators exploit MeerKAT radio observations of this binary pulsar. Thanks to the improved timing precision, they were able to model the emission geometry of the pulsar, which is now out of our line of sight, predicting that we will start reobserving pulsar B in early 2035.
