Far Ultraviolet Spectroscopic Explorer Observations of the Low-Mass X-Ray Binary 2A 1822−371 (V691 Coronae Australis)

FUSE observations were taken around the 5.57 hr binary orbit of the low-mass eclipsing X-ray binary 2A 1822-371 (V691 CrA). The spectra are presented in four phase bins, corresponding to the observing windows from the FUSE satellite. We describe the far-ultraviolet flux, the O VI emission, and their...

Zusammenfassung:FUSE observations were taken around the 5.57 hr binary orbit of the low-mass eclipsing X-ray binary 2A 1822-371 (V691 CrA). The spectra are presented in four phase bins, corresponding to the observing windows from the FUSE satellite. We describe the far-ultraviolet flux, the O VI emission, and their changes through the binary orbit, and compare them with previous optical studies.
