Direct evidence for efficient scattering of suprathermal electrons by whistler mode waves in the Martian magnetosphere

Abstract

A unique event is reported in which whistler mode waves are observed exactly corresponding to MAVEN detection of suprathermal electron dropout.• The diffusion coefficients of the whistler mode waves are calculated by using the measured electric field power.• These observations suggest that whistler mode waves can cause a decrease in the flux of suprathermal electrons (3−45 eV).

Several works have demonstrated that AKR may accelerate or scatter the energetic electrons under the proper conditions (Li et al., 2023; Summers et al., 2001; Xiao, Chen, & He, 2010; Xiao, Chen, He, & Yang, 2010; Xiao, Su, et al., 2010; Xiao et al., 2006; Zhang et al., 2020). Those accelerated (or scattered) electrons can lead to considerable damage to spacecrafts (or destruction of ozone) (Baker, 2002; Callis et al., 1998; Thorne, 1977; Thorne et al., 2005).…”
