Spectroscopic Observations of the Interstellar Medium in Emission in the Extreme Ultraviolet: Early Results from EUVE
Abstract
We present early results on the spectra of diffuse emission from the interstellar medium (ISM) using the Extreme Ultraviolet Explorer (EUVE) satellite. EUVE is performing a sensitive all-sky survey in four bandpasses across the EUV\@. During this time the Deep Survey/Spectrometer instrument is slowly scanning the ecliptic plane by pointing in the anti-sun direction. EUVE can measure diffuse spectra from 170 to 760 Angstroms with a spectral resolution from 17 to 35 Angstroms. The ISM can produce a significant flux in this band if there is enough emission measure in the temperature range from 10(5) K to 10(7) K\@. In this paper we present the diffuse EUV spectra that were taken during the beginning of the survey. We also fold plasma codes through the spectra and present the emission measure that would produce these spectra. This work has been supported by NASA contracts NAS5-30180 and NAS5-29298.
