    "abstract": "We present particle-in-cell simulations of collisionless magnetic\nreconnection in a system (like the magnetopause) with a large density asymmetry\nacross the current layer. In the presence of an ambient component of the\nmagnetic field perpendicular to the reconnection plane the gradient creates a\ndiamagnetic drift that advects the X-line with the electron diamagnetic\nvelocity. When the relative drift between the ions and electrons is of the\norder the Alfven speed the large scale outflows from the X-line necessary for\nfast reconnection cannot develop and the reconnection is suppressed. We discuss\nhow these effects vary with both the plasma beta and the shear angle of the\nreconnecting field and discuss observational evidence for diamagnetic\nstabilization at the magnetopause.",
