Future Prospects for Partially Ionised Solar Plasmas: the Prominence Case
Susanna Parenti, Manuel Luna, José Luis Ballester
Partially ionised plasmas (PIP) constitute an essential ingredient of our plasma universe. Historically, the physical effects associated with partial ionisation were considered in…
Extension and validation of the pendulum model for longitudinal solar prominence oscillations
M. Luna, J. Terradas, J. Karpen +1
Longitudinal oscillations in prominences are common phenomena on the Sun. These oscillations can be used to infer the geometry and intensity of the filament magnetic field. Previou…
One dimensional prominence threads: I. Equilibrium models
J. Terradas, M. Luna, R. Soler +3
Threads are the building blocks of solar prominences and very often show longitudinal oscillatory motions that are strongly attenuated with time. The damping mechanism responsible…
Chromospheric Heating by MHD Waves and Instabilities
A. K. Srivastava, J. L. Ballester, P. S. Cally +7
The importance of the chromosphere in the mass and energy transport within the solar atmosphere is now widely recognised. This review discusses the physics of magnetohydrodynamic (…
Alfven wave heating in partially ionized thin threads of solar prominences
Llorenc Melis, Roberto Soler, Jose Luis Ballester
There is observational evidence of the presence of small-amplitude transverse magnetohydrodynamic (MHD) waves with a wide range of frequencies in the threads of solar prominences.…
Magneto-Rossby waves in the solar tachocline and the annual variations in solar activity
Tamar Gachechiladze, Teimuraz V. Zaqarashvili, Eka Gurgenashvili +4
Annual oscillations have been detected in many indices of solar activity during many cycles. Recent multi spacecraft observations of coronal bright points revealed slow retrograde…
