Coronal Loop Expansion Properties Explained Using Separators
Joseph E. Plowman, Charles C. Kankelborg, Dana W. Longcope
One puzzling observed property of coronal loops is that they are of roughly constant thickness along their length. Various studies have found no consistent pattern of width variati…
The Density of Coronal Null Points from Hinode and MDI
Dana Longcope, Clare Parnell, Craig DeForest
Magnetic null points can be located numerically in a potential field extrapolation or their average density can be estimated from the Fourier spectrum of a magnetogram. We use both…
Gas-dynamic shock heating of post-flare loops due to retraction following localized, impulsive reconnection
D. W. Longcope, S. E. Guidoni, M. G. Linton
We present a novel model in which shortening of a magnetic flux tube following localized, three-dimensional reconnection generates strong gas-dynamic shocks around its apex. The sh…
The Number Of Magnetic Null Points In The Quiet Sun Corona
D. W. Longcope, C. E. Parnell
The coronal magnetic field above a particular photospheric region will vanish at a certain number of points, called null points. These points can be found directly in a potential f…
A Model for Patchy Reconnection in Three Dimensions
M. G. Linton, D. W. Longcope
We show, theoretically and via MHD simulations, how a short burst of reconnection localized in three dimensions on a one-dimensional current sheet creates a pair of reconnected flu…
