| Zusammenfassung |
| Over the last 10 years, the experimental
basis for the study of the local interstellar medium has been substantially
enhanced by the direct detection of interstellar pickup ions and of interstellar
neutral helium within the heliosphere. Pickup ions can be studied for a wide
range of interstellar species. However, currently the accuracy of the method to
determine the parameters of the interstellar medium, namely neutral density,
temperature and relative velocity, is hampered by two problems: (1) In most
cases the crucial ionization rates are not available from simultaneous
measurements and (2) the transport of the pickup ions in the interplanetary
medium substantially modifies the measured spatial distribution of the ions. In
this study we will discuss how the enhanced capabilities of the instrumentation
on SOHO and Cluster in combination with ongoing efforts to model the pickup ion
distributions will lead to a significant improvement over the coming years. |
