On the Genetic Relation Between Interstellar Clouds and Dust Clouds [PDF]
Symposium - International Astronomical Union, 1973 We propose that many of the denser dust clouds represent transient stages between the initiation of gravitational collapse of ordinary interstellar clouds by passage through a spiral galactic shock and the appearance of a stellar association. The interstellar gas is not processed at too rapid a rate (1) because the time spent between galactic shocks is

Abundances of Chemical Elements in Open Star Clusters as Indicators of their Nature
Open Astronomy, 2015 Applying a compilled catalog, we find that the relative abundances of α-elements in open clusters and in field stars of the thin disk of the Galaxy show different dependencies on metallicity, age and parameters of their Galactic orbits.

INTERSTELLAR CLOUDS BY SEARCHLIGHT
The Astronomical Journal, 2009 Interpretation of high-resolution observations of absorption by interstellar clouds of radiation from extragalactic sources should include the effect of the Earth's motion with respect to the source. High-resolution H I absorption profiles that are not heavily blended have been published for eight sources.

The Chemistry of Cold, Dark Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1987 In recent years the nearby cold, dark clouds have been shown to possess a rich chemistry, with interesting differences with respect to warmer massive-star-forming regions and also among the cold clouds themselves. 39 molecular species are now known in these regions.

Evidence for Spatially Distinct Galactic Dust Populations
The Astrophysical JournalWe present an implementation of a Bayesian mixture model using Hamiltonian Monte Carlo techniques to search for the spatial separation of Galactic dust populations. Utilizing intensity measurements from the Planck High Frequency Instrument, we apply this

The Astrophysical JournalIce chemistry in the dense, cold interstellar medium (ISM) is probably responsible for the formation of interstellar complex organic molecules (COMs). Recent laboratory experiments performed at T ∼ 4 K have shown that irradiation of CO:N _2 ice samples ...

Internal 1000 au Scale Structures of the R CrA Cluster-forming Cloud. I. Filamentary Structures
The Astrophysical JournalWe report Atacama Large Millimeter/submillimeter Array/Atacama Compact Array observations of a high-density region of the Corona Australis cloud forming a young star cluster, and the results of resolving internal structures. In addition to embedded Class
