Formation of All Three C2H4O Isomers—Ethylene Oxide (c-C2H4O), Acetaldehyde (CH3CHO), and Vinyl Alcohol (CH2CHOH)—in Ethanol-containing Interstellar Analog Ices

The Astrophysical Journal
Oxygen-containing complex organic molecules are key precursors to biorelevant compounds fundamental for the origins of life. However, the untangling of their interstellar formation mechanisms has just scratched the surface, especially for oxygen ...

ASTROCHEMISTRY AND INTERSTELLAR MOLECULES [PDF]

Publications of The Korean Astronomical Society, 2010
Astrochemistry provides powerful tools to understand various cosmic phenomena, including those in our solar system to the large-scale structure of the universe. In addition, the chemical property of an astronomical body is a crucial factor which governs the evolution of the system. Recent progress in astrophysical theories, computational modelings, and

Molecules in interstellar space [PDF]

Science, 2019
Astrochemistry Chemistry in space occurs wherever gas is dense and cool enough for chemical bonds to form, producing a wide variety of molecules. These are particularly common in the gas clouds that provide the raw material for star and planet formation. McGuire has cataloged all molecules detected in the interstellar and circumstellar medium.

Astrochemistry of dust, ice and gas: introduction and overview

, 2014
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 ...

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)
