Detection of periodic X-ray modulation of SFXT IGR J16207-5129 in the Swift-BAT light curve
Abstract
We report detection of a periodic intensity modulation in the Supergiant Fast X-ray Transient (SFXT) IGR J16207-5129 in the long term 15-50 keV light curve obtained with the Swift Burst Alert Telescope (BAT) between MJD 53413 and 55888. Using the Lomb-Scargle periodogram technique, we have found a period of 9.726 d. This can be the orbital period of the X-ray binary. The light curve, folded with this period shows a complex shape with a large modulation factor.
