INTERSTELLAR ABSORPTION IN SOME DIRECTIONS
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.

INTERSTELLAR MEDIUM AND DECAMETER RADIO SPECTROSCOPY [PDF]
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 ...

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 ...

Presumed Detection of C5 Molecule in the Interstellar Medium
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 ...

Turbulence in the interstellar medium [PDF]
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

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

Electronic spectroscopy of cold ions in a radio-frequency trap [PDF]
The low density of ions in mass spectrometers generally precludes direct absorption measurements. The spectrum of ions can nonetheless be obtained by using resonance two-color photofragmentation or multiphoton photofragmentation techniques.

Electronic spectroscopy of open-chain and aromatic hydrocarbon cations in neon matrices [PDF]
Considerable scientific interest has been devoted to the so-called diffuse interstellar bands (DIBs)—hundreds of absorption features of different strength and width, located in the visible and near infrared, and arising from the interstellar medium ...

Electronic spectroscopy of cold cations in a 22-pole trap by indirect methods [PDF]
The confining capabilities of a 22-pole ion trap have been employed to mea- sure electronic spectra of cations of astrophysical relevance. The ion trap sits on the head of a closed cycle cryostat, enabling collisional cooling of the confined ions with

A Reexamination of Phosphorus and Chlorine Depletions in the Diffuse Interstellar Medium
We present a comprehensive examination of interstellar P and Cl abundances based on an analysis of archival spectra acquired with the Space Telescope Imaging Spectrograph of the Hubble Space Telescope and the Far Ultraviolet Spectroscopic Explorer ...
