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

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.

Alfvén Waves in Dusty Interstellar Clouds
, 1997 Dust particles in a plasma can be higWy charged, and can carry a proportion of the negative charge of the plasma. Even if this proportion is quite small, as in interstellar dusty clouds, it can have a large effect on hydromagnetic Alfvén waves ...

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.

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 ...

Tidal stability of interstellar clouds
, 2020 The strong gravitational tidal field of supermassive black holes is thought to disrupt nearby interstellar gas clouds, preventing star formation. Recently, bipolar outflows, a "smoking- gun" for recent star formation, have been found within 2 parsecs of ...

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

Chemistry of chlorine in dense interstellar clouds [PDF]
, 1986 Laboratory experiments and theoretical modeling show that the chemistry of chlorine is fairly simple in dense interstellar clouds, with Cl and HCl as the only species whose fractional abundances are significant.

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
