Interstellar Dust at the Magnetic Wall of the Heliosphere . II
February 11, 2008 Two sets of data show that small interstellar grains captured in interstellar magnetic fields, → BIS, draped over the heliosphere appear to polarize the light of nearby stars. The polarizing grains couple to → BIS, while larger grains couple to the cloud velocity. The maximum polarization direction, Pmax, is offset in ecliptic longitude by ∆λ ∼ +35 from the upwind direction, a...

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...
متن کاملInterstellar 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 کاملImplications of Interstellar Dust and Interstellar Magnetic Field at the Heliosphere
Tiny interstellar dust grains causing the polarization of light from the nearest stars are deflected sideways in the outer heliosheath regions, along with the interstellar magnetic field. Observations of optical polarization of stars beyond the heliosphere nose, and at distances 5– 200 pc, suggest the direction of the upwind interstellar magnetic field is relatively constant. The polarization v...
