Invited talk

The plasmas in the low solar atmosphere are highly stratified and the total hydrogen density decreases about 6 orders of magnitude within a thin layer of 2 Mm. The temperature in this region is generally only several thousand K and the plasmas are partially ionized. Thanks to the high resolution telescopes, plenty of small scale reconnection events at different altitude in this region have...

45. Accelerations of energetic electrons in the Earth's inner magnetosphere: Arase observations

Yoshizumi Miyoshi (Nagoya University)

Invited talk

In the terrestrial inner magnetosphere, the energetic electron is highly variable during magnetic disturbance such as substorms and magnetic storms. The wave-particle interactions play important roles on accelerations, transportations, and loss of the energetic electrons through the cross-energy couplings. Interactions with MHD fast mode waves cause the betatron accelerations through drift...

27. Magnetic Reconnection and Electron Acceleration: Recent Insights from Microwave Imaging Spectroscopy Observations of Solar Flares

Bin Chen (New Jersey Institute of Technology)

18/11/2021, 09:00

Invited talk

Solar flares involve the catastrophic release of magnetic energy through magnetic reconnection. Solar flares are also highly efficient particle accelerators, capable of accelerating a large number of charged particles to high energies within a short time. The unique sensitivity of microwave emission to both the dynamic coronal magnetic field and the flare-accelerated high-energy electrons...
