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.

Relative Velocities between 13CO Structures within 12CO Molecular Clouds

The Astronomical Journal
Velocity fields of molecular clouds (MCs) can provide crucial information on the merger and split between clouds, as well as their internal kinematics and maintenance, energy injection and redistribution, and even star formation within clouds.

Discovery of Multiple Ultra-broad-velocity Molecular Features Associated with the W44 Molecular Cloud

The Astrophysical Journal Letters
We report the discovery of multiple compact molecular features exhibiting extremely broad velocity widths toward the W44 molecular cloud. Atacama Large Millimeter/submillimeter Array CO J = 3–2 data reveal eight “Petit-Bullets” surrounding the previously

Synthesis of Molecules in Interstellar Clouds & Star Formation [PDF]

, 1981
237-240Study of the formation and destruction processes of interstellar molecules may throw certain light on interstellar medium. Formation and destruction processes of some interstellar molecules are proposed on the basis of laboratory data.

Interstellar molecules: guides for new chemistry

, 2010
Interstellar space is among the most remarkable chemical laboratories in the universe. The existence of many unstable species with low-valent main group elements in the interstellar medium inspired us to investigate the feasibility of laboratory ...

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?

The Astrophysical Journal
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and radicals.

Regarding the Detection of Interstellar C4 and C5 Molecules

The Astrophysical Journal
Analysis of very high signal-to-noise ratio (S/N) spectra of reddened stars allowed us to determine an upper limit (UL) of the column density N (C _4 ).

Interstellar Molecules in Meteorites [PDF]

Symposium - International Astronomical Union, 1989
Substantial enrichment of deuterium, D, in certain components of chondritic meteorites is interpreted as a record of isotopic fractionation during ion-molecule reactions at the very low temperatures characteristic of dense interstellar clouds. Whether those meteorites still contain the actual molecules that were synthesised in the presolar interstellar
