Spectroscopic modeling of ionic structure in stellar winds of high-mass X-ray binaries
G. Sanjurjo-FerrÃn, V. Grinberg, I. El Mellah +6
High-mass X-ray binaries (HMXBs) provide a natural laboratory to study radiatively driven stellar winds under strong external X-ray irradiation. As the compact object moves along i…

A thousand looks at X Persei: X-ray spectroscopy at high time resolution
G. Sanjurjo-FerrÃn, J. M. Torrejón, J. J. Rodes-Roca +3
X Persei is a classical Be/X-ray binary composed of an O9.5III-B0V Be-type star and a neutron star (NS). The NS exhibits coherent pulsations with a spin period of ~837 s, orbiting…

Iron line diagnostics of the stellar wind in X1908+075
J. Planelles-Villalva, J. M. Torrejón, J. J. Rodes-Roca +1
Aims. X1908+075 is a supergiant X-ray binary (SgXB) composed of an evolved OB star and a neutron star (NS) in a 4.4-day orbit. We aim to characterize the stellar wind, constrain th…
