Parameter optimization for surface flux transport models (2017)
Journal Article
Whitbread, T., Yeates, A., Muñoz-Jaramillo, A., & Petrie, G. (2017). Parameter optimization for surface flux transport models. Astronomy & Astrophysics, 607, Article A76. https://doi.org/10.1051/0004-6361/201730689

Accurate prediction of solar activity calls for precise calibration of solar cycle models. Consequently we aim to find optimal parameters for models which describe the physical processes on the solar surface, which in turn act as proxies for what occ...

The Open Flux Problem (2017)
Journal Article
Linker, J., Caplan, R., Downs, C., Riley, P., Mikic, Z., Lionello, R., …Owens, M. (2017). The Open Flux Problem. Astrophysical Journal, 848(1), Article 70. https://doi.org/10.3847/1538-4357/aa8a70

The heliospheric magnetic field is of pivotal importance in solar and space physics. The field is rooted in the Sun's photosphere, where it has been observed for many years. Global maps of the solar magnetic field based on full-disk magnetograms are... Read More about The Open Flux Problem.

Magnetic Flux Rope Identification and Characterization from Observationally Driven Solar Coronal Models (2017)
Journal Article
Lowder, C., & Yeates, A. (2017). Magnetic Flux Rope Identification and Characterization from Observationally Driven Solar Coronal Models. Astrophysical Journal, 846(2), Article 106. https://doi.org/10.3847/1538-4357/aa86b1

Formed through magnetic field shearing and reconnection in the solar corona, magnetic flux ropes are structures of twisted magnetic field, threaded along an axis. Their evolution and potential eruption are of great importance for space weather. Here...

Reconstructing solar magnetic fields from historical observations (2017)
Journal Article
Virtanen, I., Virtanen, I., Pevtsov, A., Yeates, A., & Mursula, K. (2017). Reconstructing solar magnetic fields from historical observations. Astronomy & Astrophysics, 604, Article A8. https://doi.org/10.1051/0004-6361/201730415

Aims. We aim to use the surface flux transport model to simulate the long-term evolution of the photospheric magnetic field from historical observations. In this work we study the accuracy of the model and its sensitivity to uncertainties in its main... Read More about Reconstructing solar magnetic fields from historical observations.

Sparse reconstruction of electric fields from radial magnetic data (2017)
Journal Article
Yeates, A. (2017). Sparse reconstruction of electric fields from radial magnetic data. Astrophysical Journal, 836(1), Article 131. https://doi.org/10.3847/1538-4357/aa5c84

Accurate estimates of the horizontal electric field on the Sun's visible surface are important not only for estimating the Poynting flux of magnetic energy into the corona but also for driving time-dependent magnetohydrodynamic models of the corona....
