英文摘要 | Abstract We present a polarization analysis of PSR J0941–39 and PSR J1107–5907, which exhibit transitions between being pulsars and rotating radio transients (RRATs), using the ultrawide-bandwidth low-frequency receiver on Murriyang, the Parkes 64 m radio telescope. The spectral index of each pulsar was measured, revealing distinct variations among different states. By using the rotating vector model, we determined that the geometry of the magnetosphere remains consistent between the RRAT state and the pulsar state for PSR J0941–39, with emissions originating from the same height in the magnetosphere. The occurrence of the RRAT state could be attributed to variations in currents within the pulsar’s magnetosphere. Our results suggest that the emission mechanism of an RRAT may share similarities with that of a typical pulsar. |
