| Zusammenfassung |
| During solar flares and coronal mass
ejections, nuclei and electrons accelerated to high energies are injected into
interplanetary space. These accelerated particles can be detected at the SOHO
satellite by the ERNE instrument. From the data produced by the instrument, it
is possible to identify the particles and to calculate their energy and
direction of propagation. Depending on variable coronal/interplanetary
conditions, different kinds of effects on the energetic particle transport can
be predicted. The problems of interest include, for example, the effects of
particle properties (mass, charge, energy, and propagation direction) on the
particle transport, the particle energy changes in the transport process, and
the effects the energetic particles have on the solar-wind plasma. The evolution
of the distribution function of the energetic particles can be measured with
ERNE to a better accuracy than ever before. This gives us the opportunity to
contribute significantly to the modeling of interplanetary transport and
acceleration. Once the acceleration/transport bias has been removed, the
acceleration-site abundance of elements and their isotopes can be studied in
detail and compared with spectroscopic observations. |
