DOI: 10.1007/s11207-019-1427-5
Abstract: Hydrogen has been almost completely ignored in studies of the abundance patterns of the chemical elements in solar energetic particles (SEPs). We seek to find impulsive events where H fits these abundance patterns and document… read more here.

DOI: 10.1007/s11207-019-1431-9
Abstract: Solar energetic particles (SEPs) are released into the heliosphere by solar flares and coronal mass ejections (CMEs). They are mostly protons, with smaller amounts of heavy ions from helium to iron, and lesser amounts of… read more here.

DOI: 10.1016/j.newast.2018.12.004
Abstract: Abstract Solar energetic particles (SEP) are believed to originate from two different sources, coronal mass ejections (CMEs) and solar flares. In this paper, we have also investigated some statistical properties such as speed, apparent angular… read more here.

DOI: 10.1029/2018sw001860
Abstract: As solar activity steadily declined toward the cycle 24 minimum in the early months of 2017, the expectation for major solar energetic particle (SEP) events diminished with the sunspot number. It was thus surprising (though… read more here.

DOI: 10.1051/0004-6361/201731573
Abstract: The main sources of solar energetic particle (SEP) events are solar flares and shocks driven by coronal mass ejections (CMEs). While it is generally accepted that energetic protons can be accelerated by shocks, whether or… read more here.
