HIRDES - The High-Resolution Double-Echelle Spectrograph for the World Space Observatory Ultraviolet (WSO/UV)
K. Werner, J. Barnstedt, W. Gringel +10
The World Space Observatory Ultraviolet (WSO/UV) is a multi-national project grown out of the needs of the astronomical community to have future access to the UV range. WSO/UV cons…
The ORFEUS II Echelle Spectrometer: Instrument description, performance and data reduction
J. Barnstedt, N. Kappelmann, I. Appenzeller +11
During the second flight of the ORFEUS-SPAS mission in November/December 1996, the Echelle spectrometer was used extensively by the Principal and Guest Investigator teams as one of…
The ORFEUS II Echelle Spectrum of HD 93521: A reference for interstellar molecular hydrogen
J. Barnstedt, W. Gringel, N. Kappelmann +1
During the second flight of the ORFEUS-SPAS mission in November/December 1996, the Echelle spectrometer was used extensively by the Principal and Guest Investigator teams as one of…
ORFEUS II Echelle spectra: Molecular hydrogen at high velocities toward HD 93521
W. Gringel, J. Barnstedt, K. S. de Boer +3
Absorption lines of interstellar molecular hydrogen in the far ultraviolet (FUV) have been observed in the spectrum of the O9.5 halo star HD 93521, located some 1500 pc from the Ga…
Discovery of molecular hydrogen in a high-velocity cloud of the Galactic halo
P. Richter, K. S. de Boer, H. Widmann +4
We report the discovery of molecular hydrogen absorption in a Galactic high-velocity cloud (HVC) in the direction of the Large Magellanic Cloud. For the same HVC we derive an iron…
ORFEUS II echelle spectra: Detection of H_2 absorption in SMC gas
P. Richter, H. Widmann, K. S. de Boer +8
We present a study of molecular hyrogen (H_2) in the SMC gas, based on space shuttle Far UV spectroscopy with ORFEUS and the Tuebingen echelle spectrograph, in the line of sight to…
