Missing interstellar sulfur in inventories of polysulfanes and molecular octasulfur crowns [PDF]

Nature Communications
The disparity between predicted sulfur abundances and identified reservoirs of sulfur in cold molecular clouds, also known as the sulfur depletion problem, has remained an ongoing debate over decades.

Interstellar cloud collisions [PDF]

Monthly Notices of the Royal Astronomical Society, 1985
On decrit les resultats d'une simulation numerique en 3 dimensions de nuages interstellaires isothermes en l'absence de champs magnetiques. Les collisions, en general, ne donnent pas naissance a un ou plusieurs nuages.

Methanetetrol and the final frontier in ortho acids [PDF]

Nature Communications
The rapid dissociation of methanetetrol (C(OH)4) has been suggested as an impediment to its observation, despite the stability of its substituted derivative orthocarbonates (C(OR)4).

Laboratory detection and rotational spectroscopy of trans-HNSO: implications for astronomical observations [PDF]

Frontiers in Chemistry
Sulfur-bearing molecules are central to interstellar chemistry, yet their observed abundances in the gas phase remain far below cosmic expectations in dense interstellar regions.

An Ice Age JWST inventory of dense molecular cloud ices [PDF]

Nature Astronomy, 2023
Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and the composition of their atmospheres.

CaFe interstellar clouds [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
A new kind of interstellar cloud is proposed. These are rare (just a few examples among ∼300 lines of sight) objects with the Ca I 4227-Å, Fe I 3720-Å and 3860-Å lines stronger than those of K I (near 7699 Å) and Na I (near 3302 Å). We propose the name ‘CaFe’ for these clouds.

Creating a new paradigm for the local interstellar medium–A perspective

Frontiers in Astronomy and Space Sciences, 2023
The interstellar medium close to the Sun called the local ISM (LISM) provides critical insights into physical processes and phenomena in the more distant interstellar medium in our Galaxy without the confusion of many complex structures in the sight ...

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

Frontiers 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 ...

The Interface between the Outer Heliosphere and the Inner Local ISM: Morphology of the Local Interstellar Cloud, Its Hydrogen Hole, Strömgren Shells, and 60Fe Accretion [PDF]

Astrophysical Journal, 2019
We describe the interface between the outer heliosphere and the local interstellar medium (LISM) surrounding the Sun. The components of the inner LISM are the four partially ionized clouds (the Local Interstellar Cloud (LIC), G cloud, Blue cloud, and Aql
