Towards advanced forecasting of solar energetic particle events with the PARASOL model
Alexandr Afanasiev, Nicolas Wijsen, Rami Vainio
Gradual solar energetic particle (SEP) events are generally attributed to the particle acceleration in shock waves driven by coronal mass ejections (CMEs). Space-weather effects of…
Cross-Field Diffusion Effects on Particle Transport in a Solar Coronal Flux Rope
Edin Husidic, Nicolas Wijsen, Luis Linan +3
Solar energetic particles (SEPs) associated with solar flares and coronal mass ejections (CMEs) are key agents of space weather phenomena, posing severe threats to spacecraft and a…
Direct Measurements of Synchrotron-Emitting Electrons at Near-Sun Shocks
I. C. Jebaraj, O. V. Agapitov, M. Gedalin +22
In this study, we present the first-ever direct measurements of synchrotron-emitting heliospheric traveling shocks, intercepted by the Parker Solar Probe (PSP) during its close enc…
Cannibals in PARADISE: The effect of merging interplanetary shocks on solar energetic particle events
Antonio Niemela, Nicolas Wijsen, Angels Aran +3
Gradual solar energetic particle (SEP) events are associated with shocks driven by coronal mass ejections (CMEs). The merging of two CMEs (so-called Cannibalistic CMEs) and the int…
Calibrating the WSA model in EUHFORIA based on PSP observations
Evangelia Samara, Charles N. Arge, Rui F. Pinto +5
We employ Parker Solar Probe (PSP) observations during the latest solar minimum period (years 2018 -2021) to calibrate the version of the Wang-Sheeley-Arge (WSA) coronal model used…
Acceleration of electrons and ions by an "almost" astrophysical shock in the heliosphere
Immanuel Christopher Jebaraj, Oleksiy Agapitov, Vladimir Krasnoselskikh +18
Collisionless shock waves, ubiquitous in the universe, are crucial for particle acceleration in various astrophysical systems. Currently, the heliosphere is the only natural enviro…
Energetic particle acceleration and transport with the novel IcarusPARADISE model
Edin Husidic, Nicolas Wijsen, Tinatin Baratashvili +2
With the rise of satellites and mankind's growing dependence on technology, there is an increasing awareness of space weather phenomena related to high-energy particles. Shock wave…
Modelling ion acceleration and transport in corotating interaction regions: the mass-to-charge ratio dependence of the particle spectrum
Zheyi Ding, Gang Li, Nicolas Wijsen +2
We investigate the role of perpendicular diffusion in shaping energetic ion spectrum in corotating interaction regions (CIRs), focusing on its mass-to-charge () dependence. We…
Improved modelling of SEP event onset within the WSA-Enlil-SEPMOD framework
Erika Palmerio, Janet G. Luhmann, M. Leila Mays +14
Multi-spacecraft observations of solar energetic particle (SEP) events not only enable a deeper understanding and development of particle acceleration and transport theories, but a…
