DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES
Odessa Astronomical Publications, 2008 We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

The interstellar cloud surrounding the Sun: a new perspective
, 2014 Aims: We offer a new, simpler picture of the local interstellar medium, made of a single continuous cloud enveloping the Sun. This new outlook enables the description of a diffuse cloud from within and brings to light some unexpected properties. Methods:

The Nitrogen Chemistry in Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1987 Our time dependent model of chemistry of dense interstellar clouds has been extended to study the formation of nitrogen bearing molecules. Here we present results for the calculations, under a variety of density, temperature, and elemental conditions, of the abundances of the following observationally important species: CN, HCN, HNC, NH3, NO, and N2H.

Revisiting CN− Formation Mechanisms in Electron Collisions with Benzonitrile
ChemPhysChem, EarlyView.This study explores negative ion formation via electron attachment, revealing CN− formation at 3.0 and 7–10 eV. Dissociation pathways are analyzed using G4(MP2) and CASPT2 calculations, highlighting the coupling between the π4* and σ* resonances critical for interstellar chemistry. Radiation‐induced processes in the aromatic cyano compound benzonitrile

Structure and evolution of interstellar carbonaceous dust. Insights from the laboratory
Frontiers in Astronomy and Space Sciences, 2022 A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and evolution of these grains have been investigated for decades.

Pulsar scintillation patterns and strangelets
, 2013 We propose that interstellar extreme scattering events, usually observed as pulsar scintillations, may be caused by a coherent agent rather than the usually assumed turbulence of $\rm H_2$ clouds.

ChemPhysChem, EarlyView.Molecules with a planar tetracoordinate carbon atom serve as reactive intermediates for carbenes. While isomer 2 has been identified in the laboratory, isomer 5 remains elusive to date. Here, four stationary points with a planar tetracoordinate carbon (ptC) atom that are considered as anti‐van't Hoff Le Bel molecules have been computationally ...

, 2011 During the solar journey through galactic space, variations in the physical properties of the surrounding interstellar medium (ISM) modify the heliosphere and modulate the flux of galactic cosmic rays (GCR) at the surface of the Earth, with consequences ...

A Reanalysis of the Carbon Abundance in the Translucent Cloud toward HD 24534 [PDF]
, 1998 We have reanalyzed the Goddard High Resolution Spectrograph data set presented by Snow et al. which contains the interstellar intersystem C II] 2325A line through the translucent cloud toward HD 24534 (X Persei). In contrast to the results of Snow et al.,
