摘要: Particle acceleration is one of the most significant features that are ubiquitous among space and cosmic plasmas. It prominent during flares in case Sun, with which huge amount electromagnetic radiation high-energy particles expelled into interplanetary through plasma corona. Though it has been well understood energies supplied by mechanism called magnetic reconnection based on observations X-rays EUV telescopes, where how flaring field plasmas accelerated remained unknown due to low density We here report first observational identification energetic non-thermal electrons around point ongoing (X-point); location X-point identified soft X-ray imagery localized presence from imaging-spectroscopic data at two microwave frequencies. Considering existence outflows carries both fields out X-point, our emissions indicate X-point. Additionally, was also thermally heated up 10 MK. The estimated rate this event ~0.017.
