Far Ultraviolet observations of the High Mass X-ray Binary 4U1700-37/HD153919
R. C. Iping, G. Sonneborn, L. Kaper +1
The high-mass X-ray binary 4U1700-37/HD153919 has been observed with FUSE to study the effect of the X-ray source on the stellar wind of the primary. Phase dependent changes in the…
The radial velocity curve of HD153919 (4U1700-37) revisited
G. Hammerschlag-Hensberge, M. H. van Kerkwijk, L. Kaper
We have re-analysed all available high-resolution ultraviolet IUE spectra of the high-mass X-ray binary HD153919/4U1700-37. The radial velocity semi-amplitude of 20.6 +/- 1.0 km/s…
Modelling the orbital modulation of ultraviolet resonance lines in high-mass X-ray binaries
Jacco Th. van Loon, Lex Kaper, Godelieve Hammerschlag-Hensberge
The stellar-wind structure in high-mass X-ray binaries (HMXBs) is investigated through modelling of their ultraviolet (UV) resonance lines. For the OB supergiants in two systems, V…
Spectroscopy of HD 77581 and the mass of Vela X-1
M. H. van Kerkwijk, J. van Paradijs, E. J. Zuiderwijk +3
We present new high-resolution, high signal-to-noise optical spectra of HD 77581, the optical counterpart of the X-ray source Vela X-1, and determine radial velocities from these s…
