Direct Numerical Comparison of Data Driving Strategies for Solar Flux Emergence in Magnetohydrodynamics: B-driving vs E-driving

Kyriakos Christos Tapinou, Axel Raboonik, David I. Pontin +3

Data driving is an important technique for modelling realistic magnetic field and plasma evolution in regions of the solar atmosphere where direct observations are either absent or…

Coriolis force acting on near-surface horizontal flows during simulations of flux emergence produces a tilt angle consistent with Joy's law on the Sun

William Roland-Batty, Hannah Schunker, Robert H. Cameron +3

Joy's law describes the tilt of bipolar active regions on the Sun away from an east-west orientation, where the flux of the polarity concentrated at the prograde side tends to be c…

The Sun's open-closed flux boundary and the origin of the slow solar wind

Chloe P. Wilkins, David I. Pontin, Anthony R. Yeates +3

The Sun's open-closed flux boundary (OCB) separates closed and open magnetic field lines, and is the site for interchange magnetic reconnection processes thought to be linked to th…

A flux-independent increase in outflows prior to the emergence of active regions on the Sun

Hannah Schunker, William Roland-Batty, Aaron C. Birch +3

Emerging active regions are associated with convective flows on the spatial scale and lifetimes of supergranules. To understand how these flows are involved in the formation of act…

Evolution of the magnetic field and flows of solar active regions with persistent magnetic bipoles before emergence

Camron S. Alley, Hannah Schunker

Magnetic active regions on the Sun are harbingers of space weather events. Understanding the physics of how they form and evolve will improve space weather forecasting. Our aim is…

Understanding Active Region Emergence and Origins on the Sun and Other Cool Stars

Maria A. Weber, Hannah Schunker, Laurène Jouve +1

The emergence of active regions on the Sun is an integral feature of the solar dynamo mechanism. However, details about the generation of active-region-scale magnetism and the jour…
