Title: Alfvén wave generation during magnetic reconnection
Abstract: In the past several decades, many papers have mentioned that magnetic reconnection is crucial to the energy transfer and transport in astrophysical plasma. Through the process of magnetic reconnection, the magnetic energy can be transferred to the thermal energy and kinetic energy of plasma. Plasma kinetic energy is exported from the magnetic reconnection region in the form of waves. Various types of waves can be generated in the process of magnetic reconnection, including shear Alfvén wave. We mainly calculate the Alfvén wave energy by 2D-FFT during reconnection and then do some related analyses.

Title: Influences of sub-Alfvénic shear flows on nonlinear evolutions of secondary tearing mode instability in compressible plasmas
Abstract: The influences of shear flows during the magnetic reconnection process with the onset of the secondary magnetic island are mainly studied in the simulation. And the results about the influences of shear flows without the secondary magnetic island which we have done before will be briefly introduced. Also, the basic concepts of magnetic reconnection and MHD shocks are included in this talk.
