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 کاملExperimental Demonstration of How Strapping Fields Can Inhibit Solar Prominence Eruptions
It has been conjectured that the eruption of a solar prominence can be inhibited if a much larger scale, arched magnetic field straddles the prominence and effectively straps it down. We have demonstrated this effect in a laboratory experiment where a vacuum strapping field acts on a scaled simulation of a solar prominence. The required magnitude of the strapping field is in good agreement with...
متن کاملAutomated Detection of Solar Eruptions
Observation of the solar atmosphere reveals a wide range of motions, from small scale jets and spicules to global-scale coronal mass ejections. Identifying and characterizing these motions are essential to advancing our understanding the drivers of space weather. Both automated and visual identifications are currently used in identifying CMEs. To date, eruptions near the solar surface (which ma...
متن کاملLaboratory simulation of arched magnetic flux rope eruptions in the solar atmosphere.
Dramatic eruption of an arched magnetic flux rope in a large ambient plasma has been studied in a laboratory experiment that simulates coronal loops. The eruption is initiated by laser generated plasma flows from the footpoints of the rope that significantly modify the magnetic-field topology and link the magnetic-field lines of the rope with the ambient plasma. Following this event, the flux r...
متن کاملProminence and Filament Magnetometry Simulations
The simulations reported in this Note cover the cases of both prominence (i.e., off-limb) and filament (i.e., on-disk) observations. The various plots illustrate the statistics of the inversion of the magnetic topology—field strength (B), LOS inclination (ΘB), and POS direction (ΦB)— from different sets of 2700 synthetic observations, in the form of error scatter plots (top panels) and error hi...
