Detection asymmetry in solar energetic particle events
S. Dalla, A. Hutchinson, R. A. Hyndman +6
Context. Solar energetic particles (SEPs) are detected in interplanetary space in association with solar flares and coronal mass ejections (CMEs). The magnetic connection between t…
The multi-spacecraft high-energy solar particle event of 28 October 2021
A. Kouloumvakos, A. Papaioannou, C. O. G. Waterfall +15
Aims. We studied the first multi-spacecraft high-energy solar energetic particle (SEP) event of solar cycle 25, which triggered a ground level enhancement (GLE) on 28 October 2021,…
An analytical model of turbulence in Parker spiral geometry and associated magnetic field line lengths
T. Laitinen, S. Dalla, C. O. G. Waterfall +1
Understanding the magnetic connections from the Sun to interplanetary space is crucial for linking in situ particle observations with the solar source regions of the particles. A s…
Modelling shock-like injections of solar energetic particles with 3D test particle simulations
Adam Hutchinson, Silvia Dalla, Timo Laitinen +1
Solar Energetic Particle (SEP) acceleration and injection into interplanetary space during gradual SEP events is thought to take place at Coronal Mass Ejection (CME)-driven shocks.…
The impact of corotation on gradual solar energetic particle event intensity profiles
Adam Hutchinson, Silvia Dalla, Timo Laitinen +1
Corotation of particle-filled magnetic flux tubes is generally thought to have a minor influence on the time-intensity profiles of gradual Solar Energetic Particle (SEP) events. Fo…
Modelling the transport of relativistic solar protons along a heliospheric current sheet during historic GLE events
Charlotte O. G. Waterfall, Silvia Dalla, Timo Laitinen +2
There are many difficulties associated with forecasting high-energy solar particle events at Earth. One issue is understanding why some large solar eruptive events trigger ground l…
Energetic Proton Back-Precipitation onto the Solar Atmosphere in Relation to Long-Duration Gamma-Ray Flares
Adam Hutchinson, Silvia Dalla, Timo Laitinen +4
Gamma-ray emission during long-duration gamma-ray flare (LDGRF) events is thought to be caused mainly by 300 MeV protons interacting with the ambient plasma at or near the photo…
