Evolution and Distribution of Current Helicity in Full-Sun Simulations
A. R. Yeates, D. H. Mackay, A. A. van Ballegooijen
Current helicity quantifies the location of twisted and sheared non-potential structures in a magnetic field. We simulate the evolution of magnetic fields in the solar atmosphere i…
Exploring the Physical Basis of Solar Cycle Predictions: Flux Transport Dynamics and Persistence of Memory in Advection versus Diffusion Dominated Solar Convection Zones
A. R. Yeates, D. Nandy, D. H. Mackay
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 a…
Modelling the Global Solar Corona: Filament Chirality Observations and Surface Simulations
A. R. Yeates, D. H. Mackay, A. A. van Ballegooijen
The hemispheric pattern of solar filaments is considered in the context of the global magnetic field of the solar corona. In recent work Mackay and van Ballegooijen have shown how,…
The impact of meridional circulation on stellar butterfly diagrams and polar caps
V. Holzwarth, D. H. Mackay, M. Jardine
Observations of rapidly rotating solar-like stars show a significant mixture of opposite-polarity magnetic fields within their polar regions. To explain these observations, models…
