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.

Large Interstellar Polarisation Survey, II : UV/optical study of cloud-to-cloud variations of dust in the diffuse ISM [PDF]

, 2018
It is well known that the dust properties of the diffuse interstellar medium exhibit variations towards different sight-lines on a large scale. We have investigated the variability of the dust characteristics on a small scale, and from cloud-to-cloud. We

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Microstructure of the Local Interstellar Cloud and the Identification of the Hyades Cloud [PDF]

, 2001
We analyze high-resolution UV spectra of the Mg II h and k lines for 18 members of the Hyades Cluster to study inhomogeneity along these proximate lines of sight.

Interstellar Scintillation and Clouds of the Interstellar Turbulent Plasma [PDF]

International Astronomical Union Colloquium, 2001
AbstractData on interstellar diffraction and refraction scintillation of pulsars are analyzed. Comparison between theory and the observational data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: pure power law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has a

The density distribution and 58.4 nm radiation intensity of interstellar helium in the heliosphere: a model simulation

Earth and Planetary Physics
Research on the interstellar medium and its interaction with the solar system constitutes a significant topic in planetary physics. As the Sun traverses the local interstellar cloud, interstellar neutrals penetrate the heliosphere, forming the ...

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.

Interstellar H2 toward HD 37903

, 2011
We present an analysis of interstellar H2 toward HD 37903, which is a hot, B 1.5 V star located in the NGC 2023 reflection nebula. Meyer et al. (2001) have used a rich spectrum of vibrationally excited H2 observed by the HST to calculate a model of the ...

Prebiotic Organic Chemistry of Diketopiperazines

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

The Infrared Complex Refractive Index and Band Strengths of Coronene Thin Films

The Astrophysical Journal
Polycyclic aromatic hydrocarbon (PAH) molecules have long been theorized to be present in a multitude of interstellar environments. The radio-frequency detections of specific cyanosubstituted PAH molecules in the Taurus Molecular Cloud have provided new ...
