  • Plasma Physics
  • Space Physics
  • Astrophysics

Background:

  • Collisionless magnetic reconnection is a fundamental process in plasma physics.
  • Understanding the dynamics of reconnection in open systems is crucial for space weather and astrophysical phenomena.

Purpose of the Study:

  • To investigate steady collisionless driven reconnection in an open system.
  • To elucidate the role of ion dynamics in controlling reconnection rates and spatial structures.

Main Methods:

  • A new two-dimensional full-particle simulation was employed.
  • The simulation controlled the reconnection rate using an external driving electric field.

Main Results:

  • Ion-meandering motion was identified as a key factor in ion dynamics and spatial structures.

  • The current layer width was determined by ion-meandering orbit scales, despite electrons carrying most of the current.
  • An electrostatic field, arising from the finite-Larmor-radius effect, caused electron acceleration and ion heating.

    • Conclusions:

    • Ion dynamics dominantly control the global behavior of collisionless magnetic reconnection.
    • The simulation results align with recent experimental findings, validating the model.
    • The study highlights the importance of ion-meandering motion and finite-Larmor-radius effects in reconnection dynamics.
