Description
The data provided by the ESA INTEGRAL mission have revealed the presence
of a huge new population of HMXB sources. Among them, an important
fraction belong to the fast-growing class of Supergiant Fast X-ray
Transients (SFXT). We present a summary of our study to characterize the
outburst frequency of SFXT using INTEGRAL data corresponding to our
on-going long-term monitoring campaign. Assuming a clumpy wind accretion
scenario, the differences between SFXT and classical supergiants X-ray
emission, can be explained by simple geometrical differences in their
orbital configurations.
