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 newly born spider system at the core of a radio shell: Evidence for a low-energy supernova
S. LazareviÄ, R. Brose, L. M. Oskinova +24
In a search for low surface brightness radio nebulae using the ASKAP-EMU survey, we discovered a faint radio shell, G289.6+5.8, and its central point radio source at the position o…
Jet launching from the Kerr black hole magnetosphere: An electrogeodesic approach
Jibril Ben Achour, Ileyk El Mellah, Eric Gourgoulhon
The launch of relativistic jets of plasma on astrophysical to cosmological scales is observed in a variety of astrophysical sources, from active galactic nuclei to X-ray binaries.…
Characterizing the Post-Red Supergiant binary system AFGL 4106 and its complex nebula with SPHERE/VLT
G. Tomassini, E. Lagadec, I. El Mellah +6
Aims: We aim to characterize the physical and morphological properties of the binary system AFGL 4106, composed of two evolved massive stars. Understanding its mass-loss processes…
Interferometric view into RT Pav's long secondary period. binary vs oscillatory convective modes
B. Courtney-Barrer, X. Haubois, P. Wood +6
Long secondary periods (LSPs) occur in about one-third of evolved stars, yet their origin remains unclear. The leading explanations are oscillatory convective modes and a binary co…
Don't torque like that. Measuring compact object magnetic fields with analytic torque models
J. J. R. Stierhof, E. Sokolova-Lapa, K. Berger +10
Context. Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-s…
