Investigation of tangential and rotational discontinuities
in the solar wind at high latitude
Prof. F. M. Neubauer
Univeristy of Cologne
Abstract
In the following investigation directional discontinuities in the solar
wind, i.e. tangential and rotational discontinuities will be studied using
Ulysses magnetic field and SWOOPS plasma data. In conjunction with Helios,
Wind and Voyager data the macroscopic properties of the discontinuities and
the fine structure of the discontinuity transitions will be investigated.
The variation of physical conditions of the sun and in the solar wind as a
function of latitude will be particularly effective in the unraveling of
the physical processes determining the origin and evolution of
discontinuities. The data requested are from the time interval September
94 through March 1996 and are all in the validated data category. We shall
first identify appropriate events and then determine their nature, i.e.
tangential or rotational discontinuities or other types. This will be
followed by a classification according to finestructure of the
discontinuity transition. All this will be done for various radial
distance intervals and heliographic latitude ranges. Also we shall make
sure that the data investigated will be from comparable parts of the past
solar cycles. The interpretation of the results will lead to new insights
in plasma physics when the discontinuities are used as individual samples
from the plasma laboratory.
