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…

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…

Soft X-ray Spectral Diagnostics of Multi-thermal Plasma in Solar Flares with Chandrayaan-2 XSM

N. P. S. Mithun, Santosh V. Vadawale, Giulio Del Zanna +7

Spectroscopic observations in X-ray wavelengths provide excellent diagnostics of the temperature distribution in solar flare plasma. The Solar X-ray Monitor (XSM) onboard the Chand…

Helium line emissivities for nebular astrophysics

G. Del Zanna, P. J. Storey

We present the results of several collisional-radiative models describing optically-thin emissivities of the main lines in neutral helium formed by recombination, for a grid of ele…
