Radiography in high mass X-ray binaries -- Micro-structure of the stellar wind through variability of the column density

I. El Mellah, V. Grinberg, J. O. Sundqvist +2

In high mass X-ray binaries (HMXBs), an accreting compact object orbits a high mass star which loses mass through a dense and inhomogeneous wind. Using the compact object as an X-r…
