The interstellar absorption-line spectrum of MU Ophiuchi

open access: yesAstrophysical Journal, 1982
UV interstellar lines have been measured on high-resolution, long- and short-wavelength IUE spectra of the B8 V star Mu Oph. Column densities for the observed atoms and ions have been determined as well as turbulent velocities. The interstellar spectrum of Mu Oph is similar to the ones for Rho Oph and Zeta Oph.

Interstellar medium continuum, autoionization, and line absorption in the extreme ultraviolet

open access: yesAstronomical Journal, 1994
We provide a new estimate of the effective absorption cross section of the interstellar medium at extreme ultraviolet wavelengths. The cross section for neutral helium is discussed in detail. Two spectral features of interstellar neutral helium, the 504 A ionization edge and the autoionization resonance feature at 206 A, are detectable with existing ...

A Reexamination of Phosphorus and Chlorine Depletions in the Diffuse Interstellar Medium

open access: yesThe Astrophysical Journal, 2023
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 ...

Observations of Multiphase, High-velocity, Shocked Gas in the Vela Supernova Remnant

open access: yesThe Astrophysical Journal, 2023
We present an analysis of high-resolution far-UV archival spectra obtained with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope of the star HD 75309, which probes high-velocity shocked gas in the Vela supernova remnant (SNR).

CO TO H2 RATIO OF INTERSTELLAR MOLECULAR CLOUDS IN THE DIRECTIONS OF EARLY TYPE STARS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2004
We present measurements of interstellar CO absorption lines in the spectra of 7 early-type stars that were observed with the FUSE(Far Ultraviolet Spectroscopic Explorer).

Shaken or Stirred: The Diffuse Interstellar Medium with Exceptionally High SiO Abundance

open access: yesThe Astrophysical Journal, 2023
Interstellar shocks, a key element of stellar feedback processes, shape the structure of the interstellar medium (ISM) and are essential for the chemistry, thermodynamics, and kinematics of interstellar gas.
