| Abstract: | Summary MHD vortex flow near the heliomagnetic equatorial plane in the outer heliosphere is studied. The possibility of spiral vortex
tubes existing on both sides of the equatorial plane is shown. A structure of this type with the scale of the order of several
astronomical units can be formed during the solar minimum when the solar wind velocity has a distinct latitudinal dependence
with a minimum near the equatorial plane. Another cause of this vortex structure can be the presence of inhomogeneities of
the solar wind in the inner heliosphere. |
