Small-scale Magnetic Reconnection Events in the Sun

The Cause for the Study

• Fundamental Problems in the Solar Upper Atmosphere
  • Mass Supply
    • solar wind
    • UV downflow
    • mass inside loops (such as post-flare loops)
    • mass in the prominence
  • Mass Support and Acceleration
    • large pressure-scale height of chromosphere
    • solar wind
    • prominence eruption
    • coronal mass ejection
  • Heating
    • chromospheric heating
    • coronal heating
• Magnetic reconnection is a promising solution for these problems of
  • Mass
  • Acceleration
  • Heating
• Why do we study small-scale reconnection events?
  • a bridge between flares and nanoflares
  • not well known
  • numerosity, simplicity, and so on
