Magnetic reconnection-driven energization of protons up to 400 keV at the near-Sun heliospheric current sheet
M. I. Desai, J. F. Drake, T. Phan +22
We report observations of direct evidence of energetic protons being accelerated above ~400 keV within the reconnection exhaust of a heliospheric current sheet (HCS) crossing by NA…
