Automatic detection technique for solar filament oscillations in GONG data
Manuel Luna, Joan-René Merou Mestre, Frédéric Auchère
Solar filament oscillations have been known for decades. Now thanks to the new capabilities of the new telescopes, these periodic motions are routinely observed. Oscillations in fi…
Dark off-limb gap: manifestation of temperature minimum and dynamic nature of the chromosphere
D. Kuridze, P. Heinzel, J. Koza +1
We study off-limb emission of the lower solar atmosphere using high-resolution imaging spectroscopy in the H and Ca II 8542 Å lines obtained with the CHROMospheric Imaging Spect…
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…
Excitation of ion-acoustic waves by non-linear finite-amplitude standing Alfvén waves
Jaume Terradas, Adolfo F. - Viñas, Jaime A. Araneda
We investigate, using a multi-fluid approach, the main properties of standing ion-acoustic modes driven by nonlinear standing Alfvén waves. The standing character of the Alfvénic p…
Large-amplitude longitudinal oscillations in solar prominences simulated with different resolutions
Valeriia Liakh, Manuel Luna, Elena Khomenko
Large-amplitude longitudinal oscillations (LALOs) in solar prominences have been widely studied in the last decades. However, their damping and amplification mechanisms are not wel…
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…
