The turbulent interstellar medium [PDF]

open access: yesComptes Rendus. Physique, 2006
An overview is presented of the main properties of the interstellar medium. Evidence is summarized that the interstellar medium is highly turbulent, driven on different length scales by various energetic processes. Large-scale turbulence determines the formation of structures like filaments and shells in the diffuse interstellar medium.

Voyager Observations of Electron Densities in the Very Local Interstellar Medium

open access: yesThe Astrophysical Journal, 2023
The two Voyager spacecraft have now been immersed in the very local interstellar medium for several years. Both spacecraft carry a plasma wave instrument capable of detecting plasma waves that yield electron density through the determination of the ...

How catching the interstellar wind in the inner solar system led the way on a road to interdisciplinary research between heliophysics and astrophysics

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Combined in situ observations of the interstellar wind through the solar system and of its pickup ions (PUIs), implanted after ionization in the solar wind, explain, in comparison with interstellar absorption lines of nearby stars, that the Sun is in an ...

Determination of interstellar pickup ion distributions in the solar wind with SOHO and Cluster [PDF]

open access: yesAnnales Geophysicae, 1996
Over the last 10 years, the experimental basis for the study of the local interstellar medium has been substantially enhanced by the direct detection of interstellar pickup ions and of interstellar neutral helium within the heliosphere.

On Graphene in the Interstellar Medium [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract The possible detection of C24, a planar graphene that was recently reported to be in several planetary nebulae by García-Hernández et al., inspires us to explore whether and how much graphene could exist in the interstellar medium (ISM) and how it would reveal its presence through its ultraviolet (UV) extinction and infrared (IR)

The Interstellar Environment of our Galaxy [PDF]

open access: yes, 2001
We review the current knowledge and understanding of the interstellar medium of our galaxy. We first present each of the three basic constituents - ordinary matter, cosmic rays, and magnetic fields - of the interstellar medium, laying emphasis on their ...

A future interstellar probe on the dynamic heliosphere and its interaction with the very local interstellar medium: In-situ particle and fields measurements and remotely sensed ENAs

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

Infrared Emission from Interstellar Dust. II. The Diffuse Interstellar Medium [PDF]

open access: yes, 2001
We present a quantitative model for the infrared emission from dust in the diffuse interstellar medium. The model consists of a mixture of amorphous silicate grains and carbonaceous grains, each with a wide size distribution ranging from molecules ...

Phosphorus in the diffuse interstellar medium [PDF]

open access: yesAstronomy & Astrophysics, 2005
We present FUSE and HST/STIS measurements of the PII column density toward Galactic stars. We analyzed PII through the profile fitting of the unsaturated $ $1125 and $ $1533 lines and derived column densities integrated along the sightlines as well as in individual resolved components.

Mapping The Interstellar Medium With Near-Infrared Diffuse Interstellar Bands [PDF]

open access: yes, 2015
We map the distribution and properties of the Milky Way's interstellar medium as traced by diffuse interstellar bands (DIBs) detected in near-infrared stellar spectra from the SDSS-III/APOGEE survey.
