Magnetic clumping of charged dust in the dense interstellar medium

Context. Dust grains undergo significant growth in star-forming environments, especially in dense regions prone to gravitational collapse. Although dust is generally assumed to represent 1% of the gas mass, dust density variations are expected on small ...

Binding Energies of Interstellar Complex Organic Molecules on Water Ice Surfaces: A Quantum Chemical Investigation

The Astrophysical Journal
Interstellar dust grains are enveloped by ices of frozen molecules in cold, dense regions of the interstellar medium (ISM), which are also observed in the gas phase. Whether a species is in the solid or gaseous state is governed by its binding energy (BE)

Molecular cloud structure in the star-forming region W43

, 2013
In the struggle toward an understanding of the process of star formation it is one of the most important tasks to study the initial properties of the cold and dense interstellar medium. Stars are known to form in dense molecular clouds, but it is not yet

Interaction of hydrogen atoms with carbon-sp2 structures: adsorption energetics and Eley-Rideal dynamics

, 2011
The interaction and dynamics of hydrogen atoms on and with graphitic substrates is summarized in the light of their possible relevance for hydrogen formation in the interstellar medium.

Interstellar and Solar Nebula Materials in Cometary Dust

, 2017
Laboratory studies of cometary dust collected in the stratosphere and returned from comet 81P/Wild 2 by the Stardust spacecraft have revealed ancient interstellar grains and molecular cloud organic matter that record a range of astrophysical processes ...

Ice in space: surface science investigations of the thermal desorption of model interstellar ices on dust grain analogue surfaces

, 2010
More than 140 different molecules have been identified in the interstellar medium (ISM) to date. Dust grain particles are also found in the ISM, and some of these molecules freeze out at the cold temperatures (10-20 K) to form molecular ices ...
