Time Evolution of Elemental Ratios in Solar Energetic Particle events
P. Zelina, S. Dalla, C. M. S. Cohen +1
Heavy ion ratio abundances in Solar Energetic Particle (SEP) events, e.g.~Fe/O, often exhibit decreases over time. Using particle instruments on the ACE, SOHO and STEREO spacecraft…
Probing shock geometry via the charge to mass ratio dependence of heavy ion spectra from multiple spacecraft observations of the 2013 November 4 event
Lulu Zhao, Gang Li, G. M. Mason +5
In large SEP events, ions can be accelerated at CME-driven shocks to very high energies. Spectra of heavy ions in many large SEP events show features such as roll-overs or spectral…
Spectral properties of large gradual solar energetic particle events - II -Systematic Q/M-dependence of heavy ion spectral breaks
M. I. Desai, G. M. Mason, M. A. Dayeh +7
We fit the 0.1-500 MeV/nucleon H-Fe spectra in 46 large SEP events surveyed by Desai et al. (2016) with the double power-law Band function to obtain a normalization constant,…
Deriving the properties of coronal pressure fronts in 3-D: application to the 17 May 2012 ground level enhancement
Alexis P. Rouillard, Illya Plotnikov, Rui F. Pinto +12
We study the link between an expanding coronal shock and the energetic particles measured near Earth during the Ground Level Enhancement (GLE) of 17 May 2012. We developed a new te…
