Interstellar 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 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...
متن کاملInterstellar 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 کاملSystematic bias in interstellar magnetic field estimates
Faraday rotation of the polarization plane in magnetized thermal plasma provides one of the most efficient methods to deduce regular magnetic fields from radio astronomical observations. Since the Faraday rotation measure RM is proportional to an integral, along the line of sight, of magnetic field weighted with thermal electron density, RM is believed to yield the regular magnetic field averag...
