UK White Paper on Space-based total solar eclipse observations: structure and dynamics of the solar atmosphere
Lucie M. Green, Nicola Baresi, Huw Morgan +19
Our Sun is uniquely placed to enable a detailed study of astrophysical plasmas and how they are governed by the magnetic fields that thread through them. On the one hand, magnetic…
Understanding Solar Flares and Energetic Events: Open questions, observational requirements, and instrumental needs over the coming decade
Malcolm K. Druett, Graham S. Kerr, Joel C. Allred +15
Solar flares are the largest energy-release events in the Solar System, allowing us to study fundamental physical phenomena under extreme conditions. Those include magnetic reconne…
UK White Paper on Magnetic Reconnection
Alexander J. B. Russell, James A. McLaughlin, Philippa Browning +25
Magnetic reconnection powers explosive releases of magnetic energy, heating and particle acceleration throughout the plasma universe. Knowledge of this universal process is vital t…
Reduced atomic models for large-scale computations: Fe XIII near-infrared lines
Giulio Del Zanna, Supriya Hebbur Dayananda
Accurate atomic models for astrophysical plasma can be very complex, requiring thousands of states. However, for a variety of applications such as large-scale forward models of the…
Hinode EIS: updated in-flight radiometric calibration
G. Del Zanna, M. Weberg, H. P. Warren
We present an update to the in-flight radiometric calibration of the Hinode EUV Imaging Spectrometer (EIS), revising and extending our previous studies. We analyze full-spectral EI…
Modelling Stellar Irradiances I: the transition regions of FGKM stars
Evangelia Deliporanidou, Giulio Del Zanna
We employed advanced ionisation equilibrium models that we developed in Dufresne et. al. (2024), which include charge transfer and density effects, to model UV stellar irradiances…
