| Abstract: |
The strong hard X-ray emission of energetic electrons is observed in some solar flares. The origin of energetic electrons is, however, not known fully. Then, we suggest that the internal shocks are created in the reconnection jet in solar flares, and that energetic electrons are accelerated by the shocks. In this paper, we examine 2D MHD simulations of magnetic reconnection with a high spatial resolution. As the results, the magnetic reconnection occurs after the secondary tearing instability at the current sheet. We find that, during the non-steady Petschek reconnection, the oblique strong shocks are created by the Kelvin-Helmholtz-like instability in the reconnection jet when we assume an anomalous resistivity model. The oblique shocks can be possible sites of the particle acceleration in the solar flares. |
