Echo Tomography of Sco X-1 using Bowen Fluorescence Lines
Echo Tomography of Sco X-1 using Bowen Fluorescence Lines
We present preliminary results of a simultaneous X‐ray/optical campaign of the proto‐typical LMXB Sco X‐1 at 1–10 Hz time resolution. Lightcurves of the high excitation Bowen/HeII emission lines were obtained through narrow interference filters with ULTRACAM, and these were cross‐correlated with X‐ray lightcurves. We find evidence for correlated variability, in …
