The Origin of Prominences and Their Hemispheric Preferences for Chirality and the Skew of Overlying Loops View all abstracts by submitter

I review a ``head-to-tail'' linkage model for the formation, evolution, and eruption of solar filaments. The magnetic field structure of the model is based upon the observation that filaments form exclusively in filament channels with no apparent magnetic connections low above the polarity inversion line. The formation of a filament in this configuration is driven by flux convergence and cancellation, which produces loop-like filaments segments with a half-turn. Filament segments of like chirality may connect and form long quiescent filaments. I analyze the topology of the field in and around filaments formed through ''head-to-tail'' linkage and find consistency with the observed hemispheric preference for the skew of the X-ray emitting loops that vault the prominence, contrary to what one would expect from differential rotation.
