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" forms. The jet-sheet oscillates up and down because of a velocity shear instability. This result is due to a novel application of a state-of-the-art three-dimensional MHD code with a highly refined grid. We assume as a first approximation that the solar magnetic and rotation axes are aligned. The effect of a tilt of… 

Magnetic Effects at the Edge of the Solar System: MHD Instabilities, the de Laval Nozzle Effect, and an Extended Jet

To model the interaction between the solar wind and the interstellar wind, magnetic fields must be included. Recently, Opher et al. found that by including the solar magnetic field in a

SIMULATIONS OF WINDS OF WEAK-LINED T TAURI STARS. II. THE EFFECTS OF A TILTED MAGNETOSPHERE AND PLANETARY INTERACTIONS

Based on our previous work, we investigate here the effects on the wind and magnetospheric structures of weak-lined T Tauri stars due to a misalignment between the axis of rotation of the star and

The Effects of a Local Interstellar Magnetic Field on Voyager 1 and 2 Observations

We show that an interstellar magnetic field can produce a north-south asymmetry in the solar wind termination shock. Using Voyager 1 and 2 measurements, we suggest that the angle α between the

Consequences of Treating the Solar Magnetic Field as a Dipole on the Global Structure of the Heliosphere and Heliosheath

We investigate the effect of including the heliospheric current sheet on global modeling of the heliosphere. Due to inherent numerical dissipation in the current handling of the heliospheric current

Influence of surface stressing on stellar coronae and winds

The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic

Tearing and Kelvin-Helmholtz instabilities in the heliospheric plasma

We used 2.5D simulations to analyze the magnetohydrodynamic instabilities arising from an initial equilibrium configuration consisting of a plasma jet or wake in the presence of a magnetic field with

Confronting Observations and Modeling: The Role of the Interstellar Magnetic Field in Voyager 1 and 2 Asymmetries

Magnetic effects are ubiquitous and known to be crucial in space physics and astrophysical media. We have now the opportunity to probe these effects in the outer heliosphere with the two spacecraft

Three-dimensional Features of the Outer Heliosphere due to Coupling between the Interstellar and Interplanetary Magnetic Fields. II. The Presence of Neutral Hydrogen Atoms

We investigate the effects of coupling the interstellar and interplanetary magnetic fields (ISMF and IMF) at the heliospheric interface while taking into account the momentum and energy transfer
