Study of localized structures of kinetic Alfvén wave and generation of turbulence

Sharma, R. P.; Kumari, Anju; Yadav, Nitin

Localization of kinetic Alfvén waves (KAW) due to ponderomotive nonlinearity can be regarded as an important mechanism for heating the space plasmas. The present paper investigates the effect of background density fluctuations on the formation of large amplitude localized structures and turbulent spectrum of KAW applicable to magnetopause. The dyn…
