A hydrodynamic study of the circumstellar envelope of alpha Scorpii
K. Braun, R. Baade, D. Reimers +1
Context: Both the absolute mass-loss rates and the mechanisms that drive the mass loss of late-type supergiants are still not well known. Binaries such as alpha Sco provide the mos…
The Antares emission nebula and mass loss of alpha Sco A
D. Reimers, H. -J. Hagen, R. Baade +1
The Antares nebula is a peculiar emission nebula seen in numerous Fe II lines and in radio free-free emission, probably associated with the H II region caused by alpha Sco B in the…
HE 0515-4414 - an unusual sub-damped Ly alpha system revisited
R. Quast, D. Reimers, R. Baade
Using STIS and VLT UVES observations we have examined the ionization, abundances, and differential dust depletion of metals, the kinematic structure, and the physical conditions in…
The UV spectrum of HS1700+6416 II. FUSE observations of the HeII Lyman alpha forest
C. Fechner, D. Reimers, G. A. Kriss +11
We present the far-UV spectrum of the quasar HS1700+6416 taken with FUSE. This QSO provides the second line of sight with the HeII absorption resolved into a Ly alpha forest struct…
FUSE observations of the HeII Lyman alpha forest towards HS1700+6416
D. Reimers, C. Fechner, G. Kriss +5
We present FUSE observations of the HeII Lyman alpha forest in the redshift range 2.3 < z < 2.7 towards HS1700+6416. Between October 2002 and February 2003, the brightness of the Q…
Evolution strategies applied to the problem of line profile decomposition in QSO spectra
R. Quast, R. Baade, D. Reimers
We describe the decomposition of QSO absorption line ensembles applying an evolutionary forward modelling technique. The modelling is optimized using an evolution strategy (ES) bas…
