| contents | Forced reconnection in Voigt-regularized MHD is investigated in the Hahm-Kulsrud-Taylor problem. It is shown that Voigt regularization introduces an early linear phase of reconnection that partially bypasses the ideal current sheet formation phase. A Rutherford-like model of nonlinear island growth and saturation is introduced, including time-dependent spatial variation in the island current distribution and the braking effects of regularization and viscosity. It is conjectured, with numerical justification, that the inclusion of drag in the momentum equation results in precise MHS equilibria in the long-time limit. |
