Alfvén Waves in the Solar Atmosphere: From Theory to Observations

, 2013
Alfvén waves are considered to be viable transporters of the non-thermal energy required to heat the Sun's quiescent atmosphere. An abundance of recent observations, from state-of-the-art facilities, have reported the existence of Alfvén waves in a range

Changes in the Plasma Sheet Conditions at Europa's Orbit Retrieved From Lead Angle of the Satellite Auroral Footprints

Geophysical Research Letters
The electromagnetic interaction between Europa and the plasma sheet in the Jovian magnetosphere generates Alfvén waves, ultimately generating auroral footprints in Jupiter's atmosphere.

Cross-scale energy transfer from fluid-scale Alfvén waves to kinetic-scale ion acoustic waves in the Earth\u27s magnetopause boundary layer

In space plasmas, large-amplitude Alfvén waves can drive compressive perturbations, accelerate ion beams, and lead to plasma heating and the excitation of ion acoustic waves at kinetic scales.

Spectral study of Alfvén waves in cylindrical plasma

, 2012
Neste trabalho foi estudado o espectro das ondas de MHD ideal em um plasma cilíndrico. Considerando o plasma inomogêneo, o espectro apresenta regiões discretas e contínuas: onda lenta e onda de Alfvén.

Continuum Enhancement and Line Asymmetries of Solar Flares in Different Heating Models: Alfvén Waves, Nonthermal Electron Beams, and Their Joint Effect

The Astrophysical Journal
How the plasma in the atmosphere is heated during a solar flare remains inconclusive. Nonthermal electron beams are usually considered as an essential heating source, yet Alfvén waves have also been proposed as a promising heating mechanism.

Driven Phase-mixed Alfvén Waves in a Partially Ionized Solar Plasma

The Astrophysical Journal
Phase mixing has long been understood to be a viable mechanism for expediting the dissipation of Alfvén wave energy resulting in the subsequent heating of the solar atmosphere.

Investigation of Alfvén waves in a helicon plasma

, 2003
Helicon wave sustained discharges provide high density plasmas needed to investigate Alfvén waves under laboratory conditions. In the present paper kinetic Alfvén waves were successfully launched in a helium plasma.
