Physical Processes in the Interstellar Medium [PDF]

, 2015
Interstellar space is filled with a dilute mixture of charged particles, atoms, molecules and dust grains, called the interstellar medium (ISM). Understanding its physical properties and dynamical behavior is of pivotal importance to many areas of astronomy and astrophysics. Galaxy formation and evolution, the formation of stars, cosmic nucleosynthesis,

Voyager 1 Electron Densities in the Very Local Interstellar Medium to beyond 160 au

The Astrophysical Journal Letters
The two Voyager spacecraft have been exploring the interstellar medium beyond the heliopause since 2012 (Voyager 1) and 2018 (Voyager 2). Electron plasma oscillations and a quasi-thermal noise line at the electron plasma frequency have enabled the ...

Can the magnetic field in the Orion arm inhibit the growth of instabilities in the bow shock of Betelgeuse?

, 2013
Many evolved stars travel through space at supersonic velocities, which leads to the formation of bow shocks ahead of the star where the stellar wind collides with the interstellar medium (ISM).

A New Constraint on the Relative Disorder of Magnetic Fields between Neutral Interstellar Medium Phases

The Astrophysical Journal
Utilizing Planck polarized dust emission maps at 353 GHz and large-area maps of the neutral hydrogen (H i ) cold neutral medium (CNM) fraction ( f _CNM ), we investigate the relationship between dust polarization fraction ( p _353 ) and f _CNM in the ...

Photoelectric Emission from Interstellar Dust: Grain Charging and Gas Heating

, 2000
We model the photoelectric emission from and charging of interstellar dust and obtain photoelectric gas heating efficiencies as a function of grain size and the relevant ambient conditions.

Composition, structure and chemistry of interstellar dust [PDF]

The observational constraints on the composition of the interstellar dust are analyzed. The dust in the diffuse interstellar medium consists of a mixture of stardust (amorphous silicates, amorphous carbon, polycyclic aromatic hydrocarbons, and graphite ...
