The effects of magnetic-field geometry on longitudinal oscillations of solar prominences: Cross-sectional area variation for thin tubes
M. Luna, A. J. Diaz, R. Oliver +2
Solar prominences are subject to both field-aligned (longitudinal) and transverse oscillatory motions, as evidenced by an increasing number of observations. Large-amplitude longitu…
Observational detection of drift velocity between ionized and neutral species in solar prominences
Elena Khomenko, Manuel Collados, Antonio J. Diaz
We report a detection of differences in ion and neutral velocities in prominences using high resolution spectral data obtained in September 2012 at the German Vacuum Tower Telescop…
Evershed flow observed in neutral and singly ionized iron lines
E. Khomenko, M. Collados, N. Shchukina +1
The amplitudes of the Evershed flow are measured using pairs of carefully selected FeI and FeII spectral lines located close in wavelength and registered simultaneously. A sunspot…
Spectro-polarimetric Imaging Reveals Helical Magnetic Fields in Solar Prominence Feet
M. J. Martinez Gonzalez, R. Manso Sainz, A. Asensio Ramos +3
Solar prominences are clouds of cool plasma levitating above the solar surface and insulated from the million-degree corona by magnetic fields. They form in regions of complex magn…
Fluid description of multi-component solar partially ionized plasma
Elena Khomenko, Manuel Collados, Antonio Diaz +1
We derive self-consistent formalism for the description of multi-component partially ionized solar plasma, by means of the coupled equations for the charged and neutral components…
Time evolution of plasma parameters during the rise of a prominence instability
D. Orozco Suárez, J. A. Díaz, A. Asensio Ramos +1
We present high spatial resolution spectropolarimetric observations of a quiescent hedgerow prominence taken in the He I 1083.0 nm triplet. The observation consisted of a time seri…
