ORFEUS echelle spectra: Molecular hydrogen in disk, IVC, and HVC gas in front of the LMC
Hartmut Bluhm, Klaas. S. de Boer, Ole Marggraf +1
In front of the LMC molecular hydrogen is found in absorption near 0 km/s, being local disk gas, near +60 km/s in an intermediate velocity cloud, and near +120 km/s, in a high velo…
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…
ORFEUS II echelle spectra: deuterium and molecular hydrogen in the ISM towards BD +39 3226
H. Bluhm, O. Marggraf, K. S. de Boer +2
In ORFEUS II spectra of the sdO star BD +39 3226 interstellar hydrogen and deuterium is detected. From Ly alpha profile fitting and a curve of growth analysis of the Lyman series o…
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…
ORFEUS II echelle spectra: Absorption by H_2 in the LMC
K. S. de Boer, P. Richter, D. J. Bomans +2
We present the first detection of molecular hydrogen (H_2) UV absorption profiles on the line of sight to the LMC. The star LH 10:3120 in the LMC was measured with the ORFEUS teles…
ORFEUS II echelle spectra: The scale height of interstellar O VI in the halo
H. Widmann, K. S. de Boer, P. Richter +8
FUV high resolution spectra of 18 stars, particularly chosen to observe the interstellar medium (ISM), were obtained during the second ORFEUS-SPAS free flight space shuttle mission…
