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 کاملLong-term Geomagnetic Indices and their Use in Inferring Solar Wind Parameters in the Past
We discuss three new geomagnetic indices [the Inter-Hour Variability (IHV), Svalgaard and Cliver (2007); the Inter-Diurnal Variability (IDV), Svalgaard and Cliver, 2005; and the Polar-Cap Potential (PCP) Index, Le Sager and Svalgaard (2004)], that are derivable from data available for a century or more. Each of these indices responds directly to either the solar wind magnetic field strength (B)...
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 کاملInferring Epidemic Parameters in Networked SIS Epidemics
The mathematical modeling and analysis of epidemic spread is of great importance in understating how epidemics behave and and how to control them, and it has attracted significant interest from different communities. The study of epidemics applies to many areas such as epidemiology [1], rumor spread [2, 3], information propagation [4, 5], network security [6, 7], and viral marketing [8, 9]. Alt...
