Description
The heliospheric magnetic field, originating on the Sun, is frozen into the solar wind due to its high conductivity, and field lines are drawn out into spirals due to the rotation of the Sun. The two hemispheres of the heliosphere with oppositely directed magnetic field are separated by the so-called wavy neutral sheet. It has long been known that gradient- and curvature drift, as well as drift along the wavy neutral sheet, play a key role in cosmic-ray modulation. Previous attempts to numerically model this last effect have relied on a steady state, effective tilt angle approach to describe the neutral sheet. In this work a novel, truly time-dependent neutral sheet is introduced. Preliminary results, as to cosmic ray intensities calculated with a numerical modulation code wherein this new approach is implemented, are presented.
