TL;DR
This paper introduces a clumpy stellar wind model for OB supergiants to explain the X-ray emission patterns observed in different types of High Mass X-ray Binaries, highlighting the impact of wind inhomogeneities.
Contribution
The paper presents a new clumpy wind model specifically designed for OB supergiants to better understand X-ray variability in HMXBs.
Findings
Model successfully reproduces observed X-ray variability patterns.
Wind inhomogeneities significantly influence X-ray emission in HMXBs.
Provides insights into persistent and transient X-ray behaviors.
Abstract
We have developed a clumpy stellar wind model for OB supergiants in order to compare predictions of this model with the X-ray behaviour of both classes of persistent and transient High Mass X-ray Binaries (HMXBs).
