  • By using a method in combination with analytical and numerical methods, the paper treats the two-dimensional magnetohydrodynamic equilibria of an inviscid compressible, perfectly conducting plasma with an embedded magnetic field in the spherically symmetric gravitational field of the sun. Two different solutions are obtained. (1) Aclass of steady, self-consistent plasma flows corresponding to the structure of magnetic field consisted of the closed and open regions is given. In the open region, the radial velocity of plasma can be reached the large values exceeded the local sound speed and Alfven speed beyond the several radius of the sun. (2) The plasma velocity is always smaller than the local sound and Alfven speeds. When the radial distance is large, it tend to zero.
