Investigating Alfvénic wave propagation in coronal open-field regions [PDF]
, 2015 The physical mechanisms behind accelerating solar and stellar winds are a long-standing astrophysical mystery, although recent breakthroughs have come from models invoking the turbulent dissipation of Alfvén waves.

Atomic data and the spectrum of the solar photosphere [PDF]
Physica Scripta, 1993 Even though the solar photospheric abundances are now on the whole in very good agreement with the meteoritic values, some problems remain which will only be solved with a higher level of accuracy in the atomic data, especially the transition probabilities for faint lines.

The Astrophysical JournalWe report and discuss the phase shift and phase travel time of low-frequency ( ν < 5.0 mHz) acoustic waves estimated within the photosphere and photosphere–chromosphere interface regions, utilizing multiheight velocities in the quiet Sun.

The UK Met Office’s Coronal Mass Ejection (CME) Ensemble Prediction System
Space Weather, Volume 24, Issue 7, July 2026.Abstract We describe the 24‐member Coronal Mass Ejection (CME) ensemble prediction system that is used operationally at the UK's Met Office Space Weather Operations Center (MOSWOC) to forecast the arrival time of CMEs at Earth. The ensemble system was built on ad‐hoc assumptions and there is the need to investigate whether the technique can be improved

Solar and stellar photospheric abundances
Living Reviews in Solar Physics, 2016 The determination of photospheric abundances in late-type stars from spectroscopic observations is a well-established field, built on solid theoretical foundations. Improving those foundations to refine the accuracy of the inferred abundances has proven challenging, but progress has been made.

MAGNETOHYDRODYNAMICS OF THE WEAKLY IONIZED SOLAR PHOTOSPHERE [PDF]
The Astrophysical Journal, 2012 We investigate the importance of ambipolar diffusion and Hall currents for high-resolution comprehensive ('realistic') photospheric simulations. To do so we extended the radiative magnetohydrodynamics code \emph{MURaM} to use the generalized Ohm's law under the assumption of local thermodynamic equilibrium.
