Chemical Evolution of Some Selected Complex Organic Molecules in Low-mass Star-forming Regions
The Astrophysical Journal, 2023 The destiny of complex organic molecules (COMs) in star-forming regions is interlinked with various evolutionary phases. Therefore, identifying these species in diversified environments of identical star-forming regions would help to understand their ...

Interstellar Molecules - The Optical Region [PDF]
Highlights of Astronomy, 1971 Considerable attention has recently been given to the observation of interstellar molecules by radio methods. Interstellar molecules have also been given a boost because of excitation by the 3K black body radiation field (to use a convenient description).

Entropy Export and Chemical Reactions in Plasmas
Plasma Processes and Polymers, Volume 23, Issue 1, January 2026.In a non‐equilibrium plasma, energy is transferred to molecules by electron‐impact (1), collisions among excited molecules (2), and Joule heating (3). The entropy balance for this open system relates the energy available per molecule to changes in entropy, which determines plasma‐based gas conversion. ABSTRACT Is plasma truly a “fourth state of matter”?

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?
The Astrophysical JournalIn 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.

Adsorption of Helium on Cationic or Anionic Tetracene and Pentacene
Small Structures, Volume 7, Issue 1, January 2026.How does the arrangement of helium atoms that are adsorbed on tetracene or pentacene ions change with increasing coverage? When does the adsorption layer change from 1D to 2D, and to 3D? Is the transition abrupt? Are the helium atoms localized? Is the arrangement the same for cations and anions? What changes as the acene grows in length?

An Ultraviolet Study of CO Chemistry in the Magellanic Clouds
The Astronomical JournalHow does molecular cloud chemistry change with metallicity? In this work, we study the relation between molecular hydrogen (H _2 ) and carbon monoxide (CO) at 1/2 and 1/5 solar metallicity using ultraviolet absorption spectroscopy obtained as part of the

Microwave Evidence For Interstellar Molecules [PDF]
Highlights of Astronomy, 1971 Some time ago, optical astronomy was successful in detecting the first molecular species in interstellar space. However, these have been limited to the three diatomic molecules CH, CH+, and CN. Consideration of this list made it rather natural, after the development of microwave astronomy, for some attention to be given to a search for OH, which has a ...
