WebApr 12, 2024 · Fast magnetosonic (MS) waves have also been known as “equatorial noise” (Russell et al., 1969) as they are mostly observed near the geomagnetic equator. MS waves can interact with radiation belt electrons in various ways. They can not only accelerate radiation belt electrons through Landau resonance ...

Different from the other waves, MS wave shows the unique properties of linear ellipiticity and quasi-perpendicular propagation.
WebFeb 3, 2024 · We report a detailed observational study of two quasi-periodic fast-propagating (QFP) magnetosonic wave events that occurred on 2011 March 9 and 10, respectively. Interestingly, both the events have two wave trains (WTs): a strong main one (WT-1) and a small and weak secondary one (WT-2). WebAug 6, 2024 · Now on Wikipedia, the fast magnetosonic speed is given as ω k = c ( V a 2 + c s 2) V a 2 + c 2 which is not the same, and on a lot of papers I see the result: ω k = c ( σ ( 1 + β s 2) + β s 2 ( 1 + β s 2) ( 1 + σ) where they also suppose θ = 90 and is actually the desirable result.
