High Lundquist Number Resistive MHD Simulations of Magnetic Reconnection: Searching for Secondary Island Formation
Recently, secondary island formation due to the tearing instability of the Sweet-Parker current sheet was identified as a possible mechanism that can lead to fast reconnection (less sensitive dependence on Lundquist number S ) both in numerical simulations using Particle-in-Cell (PIC) method [Daughton et al. 2009], as well as using resistive magnetohydrodynamics (MHD) [Lapenta 2008; Bhattacharj...

متن کاملTwo-Fluid MHD Simulations of Relativistic Magnetic Reconnection
We investigate the large scale evolution of a relativistic magnetic reconnection in an electron-positron pair plasma by a relativistic two-fluid magnetohydrodynamic (MHD) code. We introduce an inter-species friction force as an effective resistivity to dissipate magnetic fields. We demonstrate that magnetic reconnection successfully occurs in our two-fluid system, and that it involves Petschek-...

متن کاملTwo-dimensional MHD simulations of relativistic magnetic reconnection
It has been recognized that magnetic reconnection process is of great importance in high-energy astrophysics. We develop a new two-dimensional relativistic resistive magnetohydrodynamic (RMHD) code, and carry out numerical simulations of magnetic reconnection. We find that outflow velocity reaches Alfvén velocity in the inflow region, and that higher Alfvén velocity provides higher reconnection...
