Supergiant fast X-ray transients (SFXTs) are recently discovered members of the expanding family of high mass X-ray binaries. They represent a population of sources which show transient activity and are associated with blue supergiant optical counterparts. To date INTEGRAL has observed 9 SFXTs; three of which have been conformed to be X-ray pulsars. The fast, transient nature of these sources makes them a challenge to study and understand. Recently, periodic behaviour has been discovered in three such systems and has been attributed to orbital motion. We present here the discovery of a 30 day period in SAX J1818.6-1703.

Abstract

Supergiant fast X-ray transients (SFXTs) are recently discovered members of the expanding family of high mass X-ray binaries. They represent a population of sources which show transient activity and are associated with blue supergiant optical counterparts. To date INTEGRAL has observed 9 SFXTs; three of which have been conformed to be X-ray pulsars. The fast, transient nature of these sources makes them a challenge to study and understand. Recently, periodic behaviour has been discovered in three such systems and has been attributed to orbital motion. We present here the discovery of a 30 day period in SAX J1818.6-1703.
