Internal Structure of the Magnetic Funnel in the Polar Heliosphere

Kislov, R. A.

According to data obtained by the Ulysses spacecraft in 2017, high-latitude current sheets have been discovered in the polar heliosphere. They have been observed during solar activity minima in 1994 and 2007 at a distance of 2–3 AU above the south pole of the Sun. The discovered current sheets formed a conical surface rotating as a whole around th…

Model of the magnetic field in the inner heliosphere with regard to radial field strength leveling in the solar corona

Veselovsky, I. S.; Lukashenko, A. T.

On the basis of experimental results from the Ulysses spacecraft, a model is proposed for calculating the magnetic field in the corona and the heliosphere in the potential approximation, which is a modification of the potential-field source-surface model. In addition to the photospheric surface and the source surface, a new demarcated spherical su…
