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…
The Yin-Yang Magnetic Flux Eruption (Yin-Yang-MFE) Code: A Global Corona Magnetohydrodynamic Code with the Yin-Yang grid
Hongyang Luo, Yuhong Fan
We describe the numerical algorithms of a global magnetohydrodynamic (MHD) code utilizing the Yin-Yang grid, called the Yin-Yang Magnetic Flux Eruption (Yin-Yang-MFE) code, suitabl…
A data-driven MHD simulation of the 2011-02-15 coronal mass ejection from Active Region NOAA 11158
Yuhong Fan, Maria D. Kazachenko, Andrey N. Afanasyev +1
We present a boundary data-driven magneto-hydrodynamic (MHD) simulation of the 2011-02-15 coronal mass ejection (CME) event of Active Region (AR) NOAA 11158. The simulation is driv…
Quantifying Energy Release in Solar Flares and Solar Eruptive Events: New Frontiers with a Next-Generation Solar Radio Facility
Bin Chen, Dale E. Gary, Sijie Yu +16
Solar flares and the often associated solar eruptive events serve as an outstanding laboratory to study the magnetic reconnection and the associated energy release and conversion p…
Solaris: A Focused Solar Polar Discovery-class Mission to achieve the Highest Priority Heliophysics Science Now
Donald M. Hassler, Sarah E Gibson, Jeffrey S Newmark +33
Solaris is a transformative Solar Polar Discovery-class mission concept to address crucial outstanding questions that can only be answered from a polar vantage. Solaris will image…
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 Emergence of a Twisted Flux Tube into the Solar Atmosphere: Sunspot Rotations and the Formation of a Coronal Flux Rope
Y. Fan
We present a 3D simulation of the dynamic emergence of a twisted magnetic flux tube from the top layer of the solar convection zone into the solar atmosphere and corona. It is foun…
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…
