Swift/BAT 15–50 keV light curve superimposed on a time-line sketch created from the Swift/XRT, RXTE/PCA, Chandra, and XMM data analysis, showing the anticorrelation between the wind and heartbeat in IGR J17091 The second Chandra observation (second green arrow) shows a fast, ionized wind, while the first XMM-Newton observation (first red arrows) and the first Chandra observation (first green arrow) lie in the heartbeat zone and do not show any detectable wind outflow. During the last XMM-Newton observation (second red arrow), the source is in a hard state. The parts with no flare are marked with red-oblique-dashed lines. Finally the green-oblique-dashed lines individuate periods without observations.
