Tidal Disruption of “Snow Clouds” by Unassociated Stars
The Astrophysical JournalIt has been suggested that star-forming galaxies may host a substantial, dark reservoir of gas in the form of planetary-mass molecular clouds that are so cold that H _2 can condense.

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.

A Fractal Origin for the Mass Spectrum of Interstellar Clouds. II. Cloud Models and Power-Law Slopes [PDF]
, 1996 Three-dimensional fractal models on grids of ~2003 pixels are generated from the inverse Fourier transform of noise with a power-law cutoff and exponentiated to give a lognormal distribution of density.

Interstellar absorptions and shocked clouds towards supernova remnant RX J0852.0-4622
, 2012 We present results of survey of interstellar absorptions towards supernova remnant (SNR) RX J0852.0-4622. The distribution of KI absorbers along the distance of the background stars is indicative of a local region (d100km/s towards three stars and ...

ChemPlusChem, EarlyView.The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Observations of the Local Interstellar Cloud [PDF]
International Astronomical Union Colloquium, 1997 AbstractConstraints on the ambient (circumsolar) interstellar medium can be derived from observations of interstellar neutrals or their derivatives in the heliosphere. New results have been recently obtained which, when combined with optical and UV observations of the nearby stars (HST-GHRS, EUVE), remove long-standing contradictions and allow us to ...

Observing the structure of the interstellar clouds [PDF]
Journal of Physics: Conference Series, 2005 We discuss some methods for characterizing the mass distribution in the interstellar clouds. This is done in the light of available observational techniques and of appropriate statistical tools capable to highlight the structural properties of the astronomical images.

The H2 Glow of a Quiescent Molecular Cloud Observed with JWST
The Astrophysical Journal LettersWe report JWST MIRI/MRS observations of the H _2 S (1) 17.04 μ m transition in two regions in the boundary of the Taurus molecular cloud. The two regions, denoted “Edge” (near the relatively sharp boundary of the ^13 CO J = 1 → 0 emission) and “Peak ...

Kinetics and Thermodynamics of Tautomerization Reactions of 1,1‐ and 1,2‐Ethenediols
International Journal of Chemical Kinetics, EarlyView.ABSTRACT Tautomerism is a common phenomenon amongst organic molecules with easily interconvertible isomers, which can impact drug action and toxicity. Here we are interested in the enols of carboxylic acids, which are known to be much less stable than their acid counterparts.
