I present the results of a systematic search for long term periodicities of the X-ray binaries ob- served with Swift Burst Alert Monitor (BAT) during the first ten years of operation. The instru- ment monitors more than 50% of the sky each day, providing long term light curves of several hundreds sources. The detection of periodicities in the light curves of X-ray binaries is a tool to understand the geometry and the emission properties of these systems. The search has been performed using the SparSpec algorithm. The periodicities detected in the Swift BAT data are compared with those detected in the RXTE ASM data with the same method. Several orbital and superorbital periodicities previously reported in literature have been detected.

Abstract
I present the results of a systematic search for long term periodicities of the X-ray binaries ob- served with Swift Burst Alert Monitor (BAT) during the first ten years of operation. The instru- ment monitors more than 50% of the sky each day, providing long term light curves of several hundreds sources. The detection of periodicities in the light curves of X-ray binaries is a tool to understand the geometry and the emission properties of these systems. The search has been performed using the SparSpec algorithm. The periodicities detected in the Swift BAT data are compared with those detected in the RXTE ASM data with the same method. Several orbital and superorbital periodicities previously reported in literature have been detected.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
