The Lyα and Lyβ Profiles in Solar Prominences and Prominence Fine Structure
Lyα and Lyβ line profiles in a solar prominence were observed with high spatial and spectral resolution with SOHO/SUMER. Within a 60 arcsec scan, we measure a very large variety of profiles: not only reversed and non-reversed profiles but also red-peaked and blue-peaked ones in both lines. Such a spatial variability is probably related to both the fine structure in prominences and the different...
متن کاملThe Fine Structure of Solar Prominences
Solar prominences and filaments (prominences projected against the solar disk) exhibit a large variety of fine structures which are well observed down to the resolution limit of ground-based telescopes. We describe the morphological aspects of these fine structures which basically depend on the type of a prominence (quiescent or active-region). Then we review current theoretical scenarios which...
متن کاملLaboratory 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 کاملSolar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence
Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
متن کاملProminence Judgements and Textual Structure in Discourse1
In this paper the perceptual evaluation of a method to analyse the information structure of a discourse (Van Donzel, 1994) is discussed. In this evaluation listeners were presented with spoken versions of a retold story in Dutch, and were asked to mark those parts in the text they perceived as being emphasized, under the assumption that these are the most salient parts of the discourse. The res...
