Polarization Diagnostics Applied to Coronal Mass Ejections and the Background Solar Wind

Sarah E Gibson, Craig E. DeForest, Curt A. de Koning +6

The ratio of radially to tangentially polarized Thomson-scattered white light provides a powerful tool for locating the 3D position of compact structures in the solar corona and in…

When Magnetic Field Lines Stretch, Snap, and Expand: A New Look at Solar Flares with L-maps

Maria D. Kazachenko, Yuhong Fan, Andrey N. Afanasyev

Understanding the three-dimensional evolution of coronal magnetic fields during solar flares remains challenging due to the lack of direct coronal field measurements. Here we combi…

Thermal signatures of tether-cutting reconnections in pre-eruption coronal flux ropes: hot central voids in coronal cavities

Y. Fan

Using a 3D MHD simulation, we model the quasi-static evolution and the onset of eruption of a coronal flux rope. The simulation begins with a twisted flux rope emerging at the lowe…

Numerical Calculation of Convection with Reduced Speed of Sound Technique

H. Hotta, M. Rempel, T. Yokoyama +2

Context. The anelastic approximation is often adopted in numerical calculation with low Mach number, such as stellar internal convection. This approximation requires frequent globa…

An MHD Model of the December 13 2006 Eruptive Flare

Y. Fan

We present a 3D MHD simulation that qualitatively models the coronal mag- netic field evolution associated with the eruptive flare that occurred on December 13, 2006 in the emergin…

Additive Self Helicity as a Kink Mode Threshold

A. Malanushenko, D. W. Longcope, Y. Fan +1

In this paper we propose that additive self helicity, introduced by Longcope and Malanushenko (2008), plays a role in the kink instability for complex equilibria, similar to twist…

The Three-dimensional Evolution of Rising, Twisted Magnetic Flux Tubes in a Gravitationally Stratified Model Convection Zone

W. P. Abbett, G. H. Fisher, Y. Fan

We present three-dimensional numerical simulations of the rise and fragmentation of twisted, initially horizontal magnetic flux tubes which evolve into emerging Omega-loops. The fl…
