Electric and Magnetic Field Variations Associated with Martian Plasma Depletion Events
Original language description
Plasma Depletion Events (PDEs) are abrupt and localized reductions in thedensity of ionospheric plasma occurring at Mars. In this paper, we examine in-situelectric and magnetic field observations from the Mars Atmospheric and Volatile Evolution(MAVEN) mission to investigate potential mechanisms underlying the formation of daysidePDEs. We show a significant increase in low-frequency (2-215 Hz) electric field wavepower within PDEs, and a considerable increase in energetic (>70 eV) electron fluxesduring the dayside events. This is indicative of local plasma heating. We propose that thesedayside PDEs are formed due to the plasma escape away from the heated region along themagnetic field lines through the extraction by an ambipolar electric field.
