The Composition of Interstellar Molecular Clouds
Space Science Reviews, 1999We consider four aspects of interstellar chemistry for comparison with comets: molecular abundances in general, relative abundances of isomers (specifically, HCN and HNC), ortho/para ratios for molecules, and isotopic fractionation, particularly for the ratio hydrogen/deuterium.

Thermal instability in magnetized interstellar clouds
Astronomical & Astrophysical Transactions, 1997Abstract The effect of a magnetic field on the ionizational-thermal acoustic instability in the cold diffuse ISM is discussed in this paper. It is found that the frozen-in magnetic field leads to new types of instabilities called “magnetoacoustic” instabilities.

Interstellar Cloud Chemistry Revisited
1987My first encounter with interstellar cloud chemistry (Bates and Spitzer 1951) took place 35 years ago. The field then had a semblance of simplicity. Absorption lines in the spectra of a number of stars had revealed the existence of molecules in interstellar space.

Dense Interstellar Cloud Chemistry
1988Significant advances in our understanding of the gas phase chemistry of dense interstellar clouds have occurred in the last few years. These advances include the delineation of the reaction pathways by which complex molecules are produced, a preliminary understanding of the varied chemistries existing in and near regions of star formation, an ...

Fragmentation of Interstellar Clouds
2014The dense cores that form stars through gravitational collapse are embedded in much larger and more rarefied expanses of gas. How the parent▶molecular cloud produces its substructure of dense cores is the problem of fragmentation. The traditional view is that the parent cloud breaks apart as it collapses in on itself.
