A Model for Spectral and Compositional Variability at High Energies in Large, Gradual Solar Particle Events (2006, methodology): “As discussed in more detail in Tylka et al. (2005), critical questions also remain.”
Heavy-Ion Elemental Abundances in Large Solar Energetic Particle Events and Their Implications for the Seed Population (2006, background): “…material from prior SEP events has subsequently been explored in a number of studies of odd compositional and spectral behavior in IP shock events (e.g., Desai et al. 2001, 2003, 2004; Channok et al. 2005) and in LSEP events (Tylka et al. 2001, 2005; Kocharov & Torsti 2003; Li & Zank 2005).”
Proton, helium, and electron spectra during the large solar particle events of October-November 2003 (2005, methodology): “events prior to this solar cycle are adapted from Turner [1995]. The 14 July 2000 spectrum has been derived from data in the work of Tylka et al.”
SOLAR RELEASE TIMES OF ENERGETIC PARTICLES IN GROUND-LEVEL EVENTS (2009, background): “In some large SEP events, however, intermediate abundances may result when remnant suprathermal ions from impulsive events contribute to the seed population accelerated by CME-driven shock waves (Mason et al. 1999; Tylka et al. 2001, 2005; Desai et al. 2003; Tylka & Lee 2006).”
The Two Sources of Solar Energetic Particles (2012, background): “(7) There are 13 GLEs among the 44 events in the Tylka et al. (2005) study of shock geometry and seed population.”
The Interaction of Successive Coronal Mass Ejections: A Review (2016, background): “There are typically significant differences between SEPs accelerated through these two mechanisms, including the duration, elemental abundances, spectra, etc. (Mason, Mazur, and Dwyer, 1999; Desai et al., 2003; Desai et al., 2006; Tylka et al., 2005).”
Estimating the frequency of extremely energetic solar events, based on solar, stellar, lunar, and terrestrial records (2012, background): “Over time, these unusual large events were interpreted [e.g., Tylka et al., 2005; Tylka and Lee, 2006] in terms of particle acceleration in quasi-perpendicular shocks of remnant seed particles remaining in the low corona and inner heliosphere from earlier flares.”
Properties of Ground Level Enhancement Events and the Associated Solar Eruptions During Solar Cycle 23 (2012, background): “However, the CME speeds are high enough to drive shocks, thus supporting the shock acceleration scenario (Tylka et al. 2005).”
The Plasma and Suprathermal Ion Composition (PLASTIC) Investigation on the STEREO Observatories (2008, background): “…“impulsive” events (Mason et al. 1999); by the interplay of shock geometry and different seed populations such as solar wind and flare suprathermals (Tylka et al. 2005); or by direct injection from the flare acceleration process (e.g. Klein and Trottet 2001, and references therein; Cane et al.…”
Dynamics of the Earth’s Particle Radiation Environment (2009, background): “…and (ii) that the abundances result from re-acceleration of suprathermal flare particles (left behind from previous flares or made available from the accompanying flare) by a coronal shock propagating nearly perpendicular to the ambient magnetic field (Tylka et al. 2005; Sandroos and Vainio 2007).”
