Interstellar Dust Inside and Outside the Heliosphere
In the early 1990s, after its Jupiter flyby, the Ulysses spacecraft identified interstellar dust in the solar system. Since then the in-situ dust detector on board Ulysses continuously monitored interstellar grains with masses up to 10−13 kg, penetrating deep into the solar system. While Ulysses measured the interstellar dust stream at high ecliptic latitudes between 3 and 5 AU, interstellar im...
متن کاملPerspectives on Interstellar Dust Inside and Outside of the Heliosphere
Measurements by dust detectors on interplanetary spacecraft appear to indicate a substantial flux of interstellar particles with masses > 10−12 g. The reported abundance of these massive grains cannot be typical of interstellar gas: it is incompatible with both interstellar elemental abundances and the observed extinction properties of the interstellar dust population. We discuss the likelihood...
متن کاملThe Galactic Environment of the Sun: Interstellar Material Inside and Outside of the Heliosphere
Interstellar material (ISMa) is observed both inside and outside of the heliosphere. Relating these diverse sets of ISMa data provides a richer understanding of both the interstellar medium and the heliosphere. The galactic environment of the Sun is dominated by warm, low-density, partially ionized interstellar material consisting of atoms and dust grains. The properties of the heliosphere are ...
متن کاملModeling the Motion and Distribution of Interstellar Dust inside the Heliosphere
The interaction of dust grains originating from the local interstellar cloud with the environment inside the heliosphere is investigated. As a consequence of this interaction the spatial distribution of interstellar dust grains changes with time. Since dust grains are charged in the interplanetary plasma and radiation environment, the interaction of small grains with the heliosphere is dominate...
متن کاملInterstellar Dust and Magnetic Field at the Heliosphere
The very weak polarization of light from nearby stars reaches a maximum near the ecliptic plane in a position offset by λ ∼ 35 from the heliosphere nose direction. The position angle for the polarization in this ecliptic-plane peak is the same for near and distant stars, to within uncertainties, indicating the interstellar magnetic field direction is relatively constant over several hundred par...
