Interstellar processes: Ortho/para conversion, radiative association, and dissociative recombination
EPJ Web of Conferences, 2015 The study of the ortho-to-para ratio of assorted gas-phase interstellar molecules such as H2, H2O, NH3, and H2O+ has gained interest in recent years, based partially on new spectral observations of light hydrides by the Herschel Space Observatory ...

Ionize Hard: Interstellar PO+ Detection
Frontiers in Astronomy and Space Sciences, 2022 We report the first detection of the phosphorus monoxide ion (PO+) in the interstellar medium. Our unbiased and very sensitive spectral survey toward the G+0.693–0.027 molecular cloud covers four different rotational transitions of this molecule, two of ...

PECULIARITIES OF MIXING METALS IN INTERGALACTIC AND INTERSTELLAR MEDIA
Odessa Astronomical Publications, 2008 We review the current status of the problem of metal mixing in the intergalactic and interstellar media. We give simple arguments for inefficiency of mixing metals because of a saturation of hydrodynamic (Rayleigh-Taylor and Kelvin-Helmholz ...

The λ Bootis phenomenon: interaction between a star and a diffuse interstellar cloud [PDF]
, 2002 The λ Bootis stars, a group of late B- to early F-type Population I stars, have surface abundances that resemble the general metal depletion pattern found in the interstellar medium.

Hierarchical structure of the interstellar molecular clouds and star formation
Open Astronomy, 2017 Properties of the hierarchical structures of interstellar molecular clouds are discussed. Particular attention is paid to the statistical correlations between velocity dispersion and size, and between the magnetic field strength and gas density.

CALCULATION OF CHEMICAL EQUILIBRIUM IN THE INTERSTELLAR CLOUD
Odessa Astronomical Publications, 2017 In order to calculate the molecular concentrations in the interstellar cloud and to obtain heir spatial distribution we have made a computational code to solve the set of equations for chemical equilibrium and equations of charge and atom balance.
