The flow of interstellar dust into the solar system

Kempf, S.; Srama, R.; Grün, E. +3 more

Context. Interstellar dust (ISD) is a major component in the formation and evolution of stars, stellar systems, and planets. Astronomical observations of interstellar extinction and polarization, and of the infrared emission of the dust, are the most commonly used technique for characterizing interstellar dust. Besides this, the interstellar dust …

Expansion of magnetic clouds in the outer heliosphere

Rodriguez, L.; Gulisano, A. M.; Démoulin, P. +1 more

Context. A large amount of magnetized plasma is frequently ejected from the Sun as coronal mass ejections (CMEs). Some of these ejections are detected in the solar wind as magnetic clouds (MCs) that have flux rope signatures.
Aims: Magnetic clouds are structures that typically expand in the inner heliosphere. We derive the expansion propertie…

Uncovering the magnetic environment of our solar system

Ben-Jaffel, L.; Ratkiewicz, R.

Since its formation 4.6 billion years ago, our solar system has most likely crossed numerous magnetized interstellar clouds and bubbles of different sizes and contents on its path through the Milky Way. Having a reference model for how the heliosphere and interstellar winds interact is critical for understanding our current Galactic environment, a…
