POLAR Investigation of the Sun - POLARIS
T. Appourchaux, P. Liewer, M. Watt +34
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the S…
Global Asymmetry of the Heliosphere
Merav Opher, Edward C. Stone, Paulett C. Liewer +1
Opher et al. 2006 showed that an interstellar magnetic field parallel to the plane defined by the deflection of interstellar hydrogen atoms can produce a north/south asymmetry in t…
Effects of a Local Interstellar Magnetic Field on Voyager 1 and 2 Observations
Merav Opher, Edward C. Stone, Paulett C. Liewer
We show that that an interstellar magnetic field can produce a north/south asymmetry in solar wind termination shock. Using Voyager 1 and 2 measurements, we suggest that the angle…
Magnetic Effects Change Our View of the Heliosheath
M. Opher, P. C. Liewer, M. Velli +5
There is currently a controversy as to whether Voyager 1 has already crossed the Termination Shock, the first boundary of the Heliosphere. The region between the Termination Shock…
Magnetic Effects at the Edge of the Solar System: MHD Instabilities, the de Laval nozzle Effect and an Extended Jet
M. Opher, P. C. Liewer, M. Velli +6
To model the interaction between the solar wind and the interstellar wind, magnetic fields must be included. Recently Opher et al. 2003 found that, by including the solar magnetic…
Probing the Edge of the Solar System: Formation of an Unstable Jet-Sheet
M. Opher, P. C. Liewer, T. I. Gombosi +4
The Voyager spacecraft is now approaching the edge of the solar system. Near the boundary between the solar system and the interstellar medium we find that an unstable ``jet-sheet'…
