To investigate the effect of asymmetric magnetic reconnection on thedevelopment of the diffusion region and growth of magnetic islands induced duringreconnection (plasmoids). we use 2-dimensional resistive magnetohydrodynamics sim-ulations. In particular. we consider the strength of the magnetic field and plasma massdensity to be dissimilar on both sides of the current sheet. https://www.rawafricaonline.com/
