Interstellar Molecules - Theory [PDF]
Symposium - International Astronomical Union, 1974 A number of possible mechanisms for the formation of molecules in the interstellar medium are discussed. Plausible suggestions have been made for the production of most of the known diatomics, but there is little understanding of polyatomics so far.

On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds
The Astrophysical Journal, 2023 We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Dust evolution, a global view: II. Top-down branching, nanoparticle fragmentation and the mystery of the diffuse interstellar band carriers [PDF]
Royal Society Open Science, 2016 The origin of the diffuse interstellar bands (DIBs), one of the longest-standing mysteries of the interstellar medium (ISM), is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS). The likely nature of

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates
The Astrophysical Journal Supplement Series, 2023 The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Modeling the processing of interstellar ices by energetic particles [PDF]
, 2013 Context. Interstellar ice is the main form of metal species in dark molecular clouds. Experiments and observations have shown that the ice is significantly processed after the freeze-out of molecules onto grains.

Molecular Hydrogen and its Proxies HCO+ and CO in the Diffuse Interstellar Medium
The Astrophysical Journal, 2023 There is a robust polyatomic chemistry in diffuse, partially molecular interstellar gas that is readily accessible in absorption at radio/millimeter/submillimeter wavelengths.

Organic Molecules in Interstellar Space: Latest Advances
Frontiers in Astronomy and Space Sciences, 2022 Although first considered as too diluted for the formation of molecules in-situ and too harsh an environment for their survival, the interstellar medium has turned out to host a rich palette of molecular species: to date, 256 species, not counting ...

Considerations Regarding Interstellar Molecules [PDF]
The Astrophysical Journal, 1937 An attempt has been made to compute the numbers of certain molecules in interstellar space. The results obtained are unfavorable to Saha's identification of one of Merrill's interstellar lines with Na2. A search for the bands of CH, OH, NH, CN, and C2 would appear to be promising.

Molecules, ices and astronomy [PDF]
, 2007 Molecules in interstellar gas and in interstellar ices play a fundamental role in astronomy. However, the formation of the simplest molecule, molecular hydrogen, is still not fully understood.
