"Unraveling the Direction of the Local Interstellar Magnetic Field: Implications for the Solar System, The ISM Turbulence and
Magnetohydrodynamic Instabilities"

Magnetic effects are ubiquitous and known to be crucial in astrophysical media; they affect shocks, accretion disks around T-Tauri, the interstellar
media, among other aspects. The twin spacecraft Voyagers are providing us with an unexpected view of how stars interact with their surrounding media. For the first time we are able to in-situ measure particles and fields of the boundaries of the solar system. Voyager 1 crossed in Dec 2004, the termination shock and is now in the heliosheath. Voyager 2 recently (Aug 2007) crossed the termination shock as well. This talk will explore the different magnetic effects able to be sampled in the solar system using state-of-the art computational models and observations. Recently, using data from Voyager 1 and 2 streaming and radio data in conjunction with state-of-the art 3D MHD modeling, we were able to constrain the direction of the local interstellar magnetic field. As a result, the solar system is asymmetric being pushed in the southern direction. I will also review our previous work that showed that Kelvin-Helmholtz instabilities and turbulence exist near the current sheets. These effects will be able to be sampled by the Voyager observations in the heliosheath. I will comment on these results and their implications as for example for the local interstellar magnetic turbulence.
