Hemispheric injection of magnetic helicity by surface flux transport (2019)
Journal Article
Hawkes, G., & Yeates, A. (2019). Hemispheric injection of magnetic helicity by surface flux transport. Astronomy & Astrophysics, 631, Article A138. https://doi.org/10.1051/0004-6361/201936475

Aims. We estimate the injection of relative magnetic helicity into the solar atmosphere by surface flux transport over 27 solar cycles (1700–2009). Methods. We determine the radial magnetic field evolution using two separate surface flux transport mo... Read More about Hemispheric injection of magnetic helicity by surface flux transport.

The need for active region disconnection in 3D kinematic dynamo simulations (2019)
Journal Article
Whitbread, T., Yeates, A., & Munoz-Jaramillo, A. (2019). The need for active region disconnection in 3D kinematic dynamo simulations. Astronomy & Astrophysics, 627, Article A168. https://doi.org/10.1051/0004-6361/201935986

In this paper we address a discrepancy between the surface flux evolution in a 3D kinematic dynamo model and a 2D surface flux transport model that has been closely calibrated to the real Sun. We demonstrate that the difference is due to the connecti... Read More about The need for active region disconnection in 3D kinematic dynamo simulations.

Reconstructing solar magnetic fields from historical observations : IV. Testing the reconstruction method (2019)
Journal Article
Virtanen, I., Virtanen, I., Pevtsov, A., Bertello, L., Yeates, A., & Mursula, K. (2019). Reconstructing solar magnetic fields from historical observations : IV. Testing the reconstruction method. Astronomy & Astrophysics, 627(A11), Article A11. https://doi.org/10.1051/0004-6361/201935606

Abstract Aims. The evolution of the photospheric magnetic field has only been regularly observed since the 1970s. The absence of earlier observations severely limits our ability to understand the long-term evolution of solar magnetic fields, especial...
