[1] Taking into account gravitation and the temperature gradient, three-dimensional MHD simulation of solar corona expansion in a dipole magnetic field was performed. Dissipation, compressibility, and anisotropy of thermal conductivity were taken into consideration. For calculations, the PERESVET code was used. It was been shown that a heliospheric current sheet having a normal component of magnetic field is formed. An important result is that the establishment of the stationary plasma outflow has been found to be extremely sensitive to the corona plasma parameters. For typical corona parameters, the flow becomes supersonic at a distance of more than three solar radii.
