Astrochemistry With the Orbiting Astronomical Satellite for Investigating Stellar Systems
Chemistry along the star- and planet-formation sequence regulates how prebiotic building blocks—carriers of the elements CHNOPS—are incorporated into nascent planetesimals and planets.

The huge variety of planetary systems discovered in recent decades likely depends on the early history of their formation. In this contribution, we introduce the FAUST Large Program which focuses specifically on the early history of solar-like protostars

On the Energetics of the HCO$^+$ + C $\to$ CH$^+$ + CO Reaction and Some Astrochemical Implications [PDF]
We explore the energetics of the titular reaction, which current astrochemical databases consider open at typical dense molecular (i.e., dark) cloud conditions.

Cretaceous-Tertiary boundary deposits in Denmark: A diachroneity [PDF]
The lateral distribution of predominantly terrestrial kerogen or humics enriched with copper(II) porphyrins (Cu-P) across the Danish marine basin implies that the alleged Cretaceous-Tertiary (KT) boundary deposits in western Denmark (at the Nye Kløv ...

Interstellar dimethyl ether gas-phase formation: a quantum chemistry and kinetics study [PDF]
Dimethyl ether is one of the most abundant interstellar complex organic molecules. Yet its formation route remains elusive. In this work, we have performed electronic structure and kinetics calculations to derive the rate coefficients for two ion ...

Dust Formation in Astrophysical Environments: The Importance of Kinetics
Astronomical observations and analysis of stardust isolated from meteorites have revealed a highly diverse interstellar and circumstellar grain inventory, including a wide range of amorphous materials and crystalline compounds (silicates and carbon ...

Astrochemistry of dust, ice and gas: introduction and overview
A brief introduction and overview of the astrochemistry of dust, ice and gas and their interplay is presented, aimed at non-specialists. The importance of basic chemical physics studies of critical reactions is illustrated through a number of recent ...

Reaction Kinetics in a Tight Spot
The standard analysis of reaction networks based on deterministic rate equations fails in confined geometries, commonly encountered in fields such as astrochemistry, thin film growth and cell biology.
