Abstract

Abstract

The effects of pressure anisotropy on the magnetic reconnection of plasma arestudied based on two-dimensional compressible MHD numerical simulation. It isfound that the growth rate of magnetic reconnection is greatly enhanced in thepresence of a small pressure anistropy (P_⊥=1.02P_//). This suggests thatmirror instability and tearing instability both affect the developmentof magnetic reconnection. In a pressure anisotropy with (P_⊥=1.02P_//) tearing mode is restricted and can't form large magneticislands.
