Structures of reconnection layers based on the ideal magnetohydrodynamic equations

A Riemann solver is used, and a set of numerical simulations are performed, to study the structures of reconnection layers in the approximation of the one-dimensional ideal MHD equations. Since the Riemann solver may solve general Riemann problems, the model used in this paper is more general than those in previous investigations on this problem. Under the conditions used in the previous investigations, the structures we obtained are the same. Our numerical simulations show quantitative agreement with those obtained through the Riemann solver. (author)
