“Cold fusion”: Formation of molecules in interstellar plasmas
Plasma Physics and Controlled Fusion, 1992A brief overview is presented of the ionic reactions that occur in interstellar gas clouds which lead to the production of the complex molecules determined in those regions. It is shown that the interstellar clouds are weakly ionized plasmas and that the chemistry is largely plasma chemistry involving sequences of ion-molecule reactions producing ...

Electromagnetic Instability of a Homogeneous Plasma in Interstellar Space
Technical Physics, 2005A study is made of an electromagnetic instability of a homogeneous plasma with an arbitrary velocity distribution in interstellar space on long time scales typical of gas-dust clouds without a significant magnetic field. It is shown that such instabilities develop on time scales of a few months or years and that it is only a narrow class of nearly ...

Effects of the Interstellar Wind on the Interplanetary Plasma
1961It is pointed out that the interstellar gas which passes through the solar system may affect the interplanetary gas, planetary atmospheres, and the orbits of satellites. This paper discusses the interaction of the interplanetary and interstellar gases via atomic collisions.

Scintillation as a tool for studying the interstellar plasma
Radiophysics and Quantum Electronics, 1994The interstellar plasma is characterized by variations of electron density having a wide range of physical scales. Radiation propagating through this inhomogeneous plasma is scattered, causing the received intensity to scintillate on a variety of time scales.

Performance of the Cosmic Hot Interstellar Plasma Spectrometer
SPIE Proceedings, 2003The Cosmic Hot interstellar Plasma Spectrometer (CHIPS), successfully launched on 2003 January 12, provides astronomers with an observatory dedicated to observation of the hot interstellar medium in the extreme ultraviolet. We describe here the otpical and photometric performance of the spectrograph based on calibrations of the individual components ...

Ionic reactions in atmospheric, interstellar and laboratory plasmas
Contemporary Physics, 1988Abstract The ionic reactions that can occur in ionized gases, and especially those in naturally-occurring low-temperature gaseous plasmas, are discussed. These reactions include several types of positive ion and negative ion reactions with molecules, ion-electron dissociative recombination reactions, electron attachment reactions and ion-ion mutual ...

The electron density in clouds of turbulent interstellar plasma
Astronomy Reports, 2016The dependence of the emission measure on the dispersion measure due to the Galactic background has been derived for 120 directions in the Galaxy. This analysis has yielded the mean electron density, effective thickness of the electron layer, and the volume filling factor of the clouds of ionized gas along the line of sight.

Ionic Processes in Low Temperature Interstellar Molecular Plasmas
AIP Conference Proceedings, 2002Astrophysical plasmas vary widely in their temperatures and compositions. Some of the most tenuous, coldest, and spatially extensive are the diffuse and dense interstellar clouds, in the latter of which stars are forming. In these regions, including circumstellar shells, ∼130 molecules have been detected with ∼10% being ions.
