Potential role of kinetic Alfvén waves and whistler waves in solar wind plasmas

摘要: Spacecraft observations indicate the signatures of highly oblique kinetic Alfven waves (KAWs) and whistler in solar wind plasma. In present work, we explore possible role KAWs observed magnetic turbulent spectrum. The nonlinear spatial evolution KAW is studied including effects ponderomotive force which results intense localized structures due to background density modification. Weak quasi-transverse wave propagating through these also gets form small-scale structures. We numerically calculated power spectra for both as well wave. Our obtained demonstrate important that play energy cascading from larger smaller scales. relevance recent spacecraft pointed out.
