Global Coronal Equilibria with Solar Wind Outflow (2021)
Journal Article
Rice, O. E., & Yeates, A. R. (2021). Global Coronal Equilibria with Solar Wind Outflow. Astrophysical Journal, 923(1), Article 57. https://doi.org/10.3847/1538-4357/ac2c71

Given a known radial magnetic field distribution on the Sun’s photospheric surface, there exist wellestablished methods for computing a potential magnetic field in the corona above. Such potential fields are routinely used as input to solar wind mode... Read More about Global Coronal Equilibria with Solar Wind Outflow.

A Comparison of Sparse and Non-sparse Techniques for Electric-Field Inversion from Normal-Component Magnetograms (2021)
Journal Article
Mackay, D., & Yeates, A. (2021). A Comparison of Sparse and Non-sparse Techniques for Electric-Field Inversion from Normal-Component Magnetograms. Solar Physics, 296(12), Article 178. https://doi.org/10.1007/s11207-021-01924-z

An important element of 3D data-driven simulations of solar magnetic fields is the determination of the horizontal electric field at the solar photosphere. This electric field is used to drive the 3D simulations and inject energy and helicity into th...

Intrinsic winding of braided vector fields in tubular subdomains (2021)
Journal Article
Prior, C. B., & Yeates, A. R. (2021). Intrinsic winding of braided vector fields in tubular subdomains. Journal of Physics A: Mathematical and Theoretical, 54(46), Article 465701. https://doi.org/10.1088/1751-8121/ac2ea3

Braided vector fields on spatial subdomains which are homeomorphic to the cylinder play a crucial role in applications such as solar and plasma physics, relativistic astrophysics, fluid and vortex dynamics, elasticity, and bio-elasticity. Often the v... Read More about Intrinsic winding of braided vector fields in tubular subdomains.

Evolution of Field Line Helicity in Magnetic Relaxation (2021)
Journal Article
Yeates, A., Russell, A., & Hornig, G. (2021). Evolution of Field Line Helicity in Magnetic Relaxation. Physics of Plasmas, 28(8), Article 082904. https://doi.org/10.1063/5.0059756

Plasma relaxation in the presence of an initially braided magnetic field can lead to self-organization into relaxed states that retain non-trivial magnetic structure. These relaxed states may be in conflict with the linear force-free fields predicted... Read More about Evolution of Field Line Helicity in Magnetic Relaxation.

Two Classes of Eruptive Events During Solar Minimum (2021)
Journal Article
Bhowmik, P., & Yeates, A. (2021). Two Classes of Eruptive Events During Solar Minimum. Solar Physics, 296(7), Article 109. https://doi.org/10.1007/s11207-021-01845-x

During solar minimum, the Sun is relatively inactive with few sunspots observed on the solar surface. Consequently, we observe a smaller number of highly energetic events such as solar flares or coronal mass ejections (CMEs), which are often associat...
