The statistical significance of the N-S asymmetry of solar activity revisited
M. Carbonell, J. Terradas, R. Oliver +1
The main aim of this study is to point out the difficulties found when trying to assess the statistical significance of the North-South asymmetry (hereafter SSNSA) of the most usua…
The effect of the solar corona on the attenuation of small-amplitude prominence oscillations. I. Longitudinal magnetic field
R. Soler, R. Oliver, J. L. Ballester
Context. One of the typical features shown by observations of solar prominence oscillations is that they are damped in time and that the values of the damping times are usually bet…
Spectral line width decrease in the solar corona: resonant energy conversion from Alfv{é}n to acoustic waves
T. V. Zaqarashvili, R. Oliver, J. L. Ballester
Observations reveal an increase with height of the line width of several coronal spectral lines probably caused by outwardly propagating Alfv{é}n waves. However, the spectral line…
Rossby waves in "shallow water" magnetohydrodynamics
T. V. Zaqarashvili, R. Oliver, J. L. Ballester +1
The influence of a toroidal magnetic field on the dynamics of Rossby waves in a thin layer of ideal conductive fluid on a rotating sphere is studied in the "shallow water" magnetoh…
