Overview

3D simulations reveal multithermal emissions and plasmoids during magnetic reconnection in the solar atmosphere, indicating new insights into solar phenomena.

Key Points

  • Magnetic reconnection formed plasmoids, resulting in temperatures above 20,000 K alongside cooler plasmas under 10,000 K.
  • During simulations, characteristic events such as Ellerman bombs and UV bursts were observed over a range of altitudes, highlighting solar atmospheric dynamics.
  • Using advanced 3D radiation magnetohydrodynamic methods, the study explores flux emergence and its relation to lower solar atmosphere emissions.
  • Findings suggest turbulent reconnection mediated by plasmoids explains interactions of UV bursts with cooler plasma features.
