A Possible Unified Picture for the Connected Recurrent Magnetic Dipolarization, Quasi‐Periodic ENA Enhancement, SKR Low‐Frequency Extension and Narrowband Emission at Saturn.

Magnetic Dipolarization, a hallmark indicator of the formation of field‐aligned currents, plays a crucial role in the energy dissipative processes that occur within planetary magnetospheres. Saturn's magnetic dipolarization was found to recur after one planetary rotation, suggesting a potential correlation with the corotating current systems. The observation of enhanced Energetic Neutral Atoms (ENA) within Saturn's inner magnetosphere serves as a diagnostic tool, revealing the existence of a rotating, dynamic Partial Ring Current (PRC) system. By utilizing multiple datasets from Cassini, this study advances the understanding of the interrelationship between ENA emission and magnetic dipolarization. Our results suggest the possibility of a coupling between the PRC system revealed by the ENA emission and magnetic dipolarization. Furthermore, a temporal correlation was found between the ENA emissions and two distinct radio emissions. This study discusses potential causal relationships among these phenomena and first time proposes a global unified physical picture. Plain Language Summary: Energy dissipation and circulation are the core of the space plasma field, which shows different typical features at different planets. Unlike the solar wind‐driven terrestrial magnetosphere, the giant planetary magnetospheric processes are strongly controlled by internal processes, and show strong rotational modulation in the in situ and remote sensing measurements. The rotation modulation of the observations in Saturn's magnetosphere may lead to challenges in the interpretation of data. The observed variations in data are a combination of spatial and temporal variations. In this study, we analyzed the multiple datasets from Cassini to formulate a uniform picture of the periodic variations including magnetic field variation, rotating hot plasma cloud, and radio emissions. We propose that the corotating current system could potentially connect all observed phenomena.
