Evolution and distribution of current helicity in full-Sun simulations (2008)
Journal Article
Yeates, A., Mackay, D., & van Ballegooijen, A. (2008). Evolution and distribution of current helicity in full-Sun simulations. Astrophysical Journal Letters, 680(2), L165-L168. https://doi.org/10.1086/590057

Current helicity quantifies the location of twisted and sheared nonpotential structures in a magnetic field. We simulate the evolution of magnetic fields in the solar atmosphere in response to flux emergence and shearing by photospheric motions. In o...

Where do solar filaments form? Consequences for theoretical models. (2008)
Journal Article
Mackay, D., Gaizauskas, V., & Yeates, A. (2008). Where do solar filaments form? Consequences for theoretical models. Solar Physics, 248(1), 51-65. https://doi.org/10.1007/s11207-008-9127-6

This paper examines the locations where large, stable solar filaments form relative to magnetic bipoles lying underneath them. The study extends the earlier work of F. Tang to include two additional classification categories for stable filaments and... Read More about Where do solar filaments form? Consequences for theoretical models..

Exploring the physical basis of solar cycle predictions: Flux transport dynamics and persistence of memory in advection versus diffusion-dominated solar convection zones (2008)
Journal Article
Yeates, A., Nandy, D., & Mackay, D. (2008). Exploring the physical basis of solar cycle predictions: Flux transport dynamics and persistence of memory in advection versus diffusion-dominated solar convection zones. Astrophysical Journal, 673(1), 544-556. https://doi.org/10.1086/524352

The predictability, or lack thereof, of the solar cycle is governed by numerous separate physical processes that act in unison in the interior of the Sun. Magnetic flux transport and the finite time delay that it introduces, specifically in the so-ca...

Modelling the global solar corona II: Coronal evolution and filament chirality comparison (2008)
Journal Article
Yeates, A., Mackay, D., & van Ballegooijen, A. (2008). Modelling the global solar corona II: Coronal evolution and filament chirality comparison. Solar Physics, 247(1), 103-121. https://doi.org/10.1007/s11207-007-9097-0

This paper considers the hemispheric pattern of solar filaments using newly developed simulations of the real photospheric and 3D coronal magnetic fields over a six-month period, on a global scale. The magnetic field direction in the simulation is co... Read More about Modelling the global solar corona II: Coronal evolution and filament chirality comparison.
