M. Jarry, C. Palmroos, E. Lavasa +12
The SPEARHEAD (specification, analysis, and re-calibration of high-energy particle data) project, funded by the European Union Horizon Europe programme, enhances the accuracy and u…
Coronal flux tube illuminated by strong shock spot: New Year's Eve solar eruption of 2023-Dec-31
Illya Plotnikov, Alexis P. Rouillard, Athanasios Kouloumvakos +1
Powerful solar eruptions are known to produce fast and wide shock waves in the solar corona and inner heliosphere. The relationship between the coronal shock waves, solar energetic…
The high-energy protons of the ground level enhancement (GLE74) event on 11 May 2024
A. Papaioannou, A. Mishev, I. Usoskin +19
High energy solar protons were observed by particle detectors aboard spacecraft in near-Earth orbit on May 11, 2024 and produced the 74th ground level enhancement (GLE74) event reg…
Generalized Two Thermal Regimes Approach : Bipoly Fluid Modeling
J-B. Dakeyo, P. Démoulin, A. P. Rouillard +3
The isopoly bi-fluid approach assumes an isothermal evolution of the solar wind near the Sun up to the radial distance riso, followed by a polytropic evolution constrained by the o…
