Far Ultraviolet Spectroscopic Explorer Observations of RX J0513.9−6951

Far Ultraviolet Spectroscopic Explorer (FUSE) observations were obtained in 2003 July during 1.2 cycles of the 0.76 day binary orbit of RX J0513.9-6951. Radial velocity measurements of the broad O VI emission profile show a semiamplitude of K ~ 26 km s-1, which is much smaller than the value of 117...

description Far Ultraviolet Spectroscopic Explorer (FUSE) observations were obtained in 2003 July during 1.2 cycles of the 0.76 day binary orbit of RX J0513.9-6951. Radial velocity measurements of the broad O VI emission profile show a semiamplitude of K ~ 26 km s-1, which is much smaller than the value of 117 km s-1 measured from 2001 FUSE data. Narrow O VI emissions show no measurable velocity variation. The mean velocity of the broad O VI emission is redshifted by ~500 km s-1 with respect to both the systemic and narrow emission-line velocities. Spectral difference plots show phase-related changes in the broad emission profile. Other phase-related changes, such as line and continuum variations, are also smaller than those in the 2001 spectra. We describe a moving broad absorption feature near 1020 A as a possible O VI outflow associated with a precessing jet. We discuss the implications for the stellar masses if the 2003 broad O VI velocities outline the compact star's orbital motion.
