Laboratory simulations of solar prominence eruptions*
Spheromak technology is exploited to create laboratory simulations of solar prominence eruptions. It is found that the initial simulated prominences are arched, but then bifurcate into twisted secondary structures which appear to follow fringing field lines. A simple model explains many of these topological features in terms of the trajectories of field lines associated with relaxed states, i.e...
متن کاملMay 29, 2002
I apologize both to Jane Fountain and to my fellow workshop participants for the lateness of this memo, which reflects both an overwrought end-of-semester schedule and a certain diffidence stemming from my lack of expertise in the topic of the workshop. My own empirical research on digital technologies has dealt with how typical Americans – that is, the cross-section of folks that a well design...
متن کاملEUV lines observed with EIS/Hinode in a solar prominence
Context. During a multi-wavelength observation campaign with Hinode and ground-based instruments, a solar prominence was observed for three consecutive days as it crossed the western limb of the Sun in April 2007. Aims. We report on observations obtained on 26 April 2007 using EIS (Extreme ultraviolet Imaging Spectrometer) on Hinode. They are analysed to provide a qualitative diagnostic of the ...
متن کاملCoronal transverse magnetohydrodynamic waves in a solar prominence.
Solar prominences are cool 10(4) kelvin plasma clouds supported in the surrounding 10(6) kelvin coronal plasma by as-yet-undetermined mechanisms. Observations from Hinode show fine-scale threadlike structures oscillating in the plane of the sky with periods of several minutes. We suggest that these represent Alfvén waves propagating on coronal magnetic field lines and that these may play a role...
متن کاملThe effect of the solar corona on the attenuation of small-amplitude prominence oscillations
Context. Observations show that small-amplitude prominence oscillations are usually damped after a few periods. This phenomenon has been theoretically investigated in terms of non-ideal magnetoacoustic waves, non-adiabatic effects being the best candidates to explain the damping in the case of slow modes. Aims. We study the attenuation of non-adiabatic magnetoacoustic waves in a slab prominence...
