WebAug 22, 2024 · This bright line is a result of Bowen fluorescence of O i powered by Lyβ photons (Appendix C). Clearly, Lyβ must be scattered into the shadow cylinder. We make the simplistic assumption that the scattered photons "fill up the trough" in Figure 8. GALEX observations were conducted for less than a quarter of the orbit. WebDec 14, 2024 · Inspired by our work on the LMXB Sco X-1 (Steeghs & Casares 2002, herefater SC) we are pursuing the detection of the companion star via Bowen fluorescence emission due to X-ray irradiation. The combination of velocity information and light curves enable us to locate the site of the main emission/absorption lines whithin the binary.
