Interstellar X-Ray Absorption and Scattering

open access: yesThe Astrophysical Journal
Accurate estimates of the absorption of X-rays by interstellar gas and dust are of crucial importance for the analysis and interpretation of almost all astronomical soft X-ray observations.

INTERSTELLAR ABSORPTION IN SOME DIRECTIONS

open access: yesOdessa Astronomical Publications, 2017
Interstellar absorption has been investigated towards Captain Areas KA-64, KA-65, KA-86, KA-87, KA- 88, KA-98 by the method of a colour excess. The star magnitudes V and colour indexes (B-V) of stars were received by Yasinskaya et al.

Variations of Interstellar Ultra-Violet Absorption [PDF]

open access: yesSymposium - International Astronomical Union, 1973
It is shown that mixtures of graphite core-ice mantle grains with large and small mean size and graphite grains provide good fits to the observed interstellar extinction curve.

A reanalysis of interstellar OH absorption observations [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1996
We reconsider the rotational analysis of the absorption electronic A-X and D-X band systems of OH and show that interstellar observations of OH in front of bright stars have been interpreted with oscillator strengths that are too small by a factor of 2.

INTERSTELLAR MEDIUM AND DECAMETER RADIO SPECTROSCOPY [PDF]

open access: yesRadio Physics and Radio Astronomy, 2021
Purpose: The analytical review of the main results of research in the new direction of the low-frequency radio astronomy, the interstellar medium radio spectroscopy at decameter waves, which had led to astrophysical discovery, recording of the radio ...

Presumed Detection of C5 Molecule in the Interstellar Medium

open access: yesThe Astrophysical Journal, 2022
The paper suggests the presence of the carbon chain C _5 molecule in translucent, interstellar H i clouds. This species, the only five atom interstellar molecule, observable in dark, translucent clouds, seems to be observable in reasonably dense clouds ...

How catching the interstellar wind in the inner solar system led the way on a road to interdisciplinary research between heliophysics and astrophysics

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Combined in situ observations of the interstellar wind through the solar system and of its pickup ions (PUIs), implanted after ionization in the solar wind, explain, in comparison with interstellar absorption lines of nearby stars, that the Sun is in an ...

INVESTIGATION OF DIFFUSE INTERSTELLAR BANDS OF ORGANIC MOLECULES IN THE SPECTRA OF CEPHEID STARS

open access: yesOdessa Astronomical Publications, 2016
We describe an effective method of investigation of the Diffuse Interstellar Bands (DIBs) in the spectra of Cepheid stars. DIBs are believed to originate from the absorption of such carriers as polycyclic aromatic hydrocarbons in the interstellar gaseous
