INTEGRAL long-term monitoring of the supergiant fast X-ray transient XTE J1739-302
Abstract
Context: In the past few years, a new class of high mass X-ray binaries (HMXRB) has been claimed to exist, the supergiant fast X-ray transients (SFXT). These are X-ray binary systems with a compact companion orbiting a supergiant star which show very short and bright outbursts in a series of activity periods overimposed on longer quiescent periods. Only very recently the first attempts to model the behaviour of these sources have been published, some of them within the framework of accretion from clumpy stellar winds.
Aims: Our goal is to analyze the properties of
Methods: We have used INTEGRAL and RXTE/PCA observations to obtain broad band (1-200 keV) spectra and light curves of
Results: We have found that
