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.…
Variable structures in the stellar wind of the HMXB Vela X-1
L. Abalo, P. Kretschmar, F. Fürst +9
Strong stellar winds are an important feature in wind-accreting high-mass X-ray binary (HMXB) systems, providing insights into stellar evolution and their impact on surrounding env…
Revisiting the archetypical wind accretor Vela X-1 in depth -- A case study of a well-known X-ray binary and the limits of our knowledge
Peter Kretschmar, Ileyk El Mellah, Silvia Martínez-Núñez +9
Context: Vela X-1 is one of the best studied X-ray binaries. Frequently though, specific values for its parameters have been used in subsequent studies without considering alternat…
Wind morphology around cool evolved stars in binaries: the case of slowly accelerating oxygen-rich outflows
I. El Mellah, J. Bolte, L. Decin +2
The late stellar evolutionary phases of low and intermediate-mass stars are strongly constrained by their mass-loss rates. The wind surrounding cool evolved stars frequently shows…
Vela X-1 as a laboratory for accretion in High-Mass X-ray Binaries
P. Kretschmar, S. Martínez-Núñez, F. Fürst +7
Vela X-1 is an eclipsing high mass X-ray binary (HMXB) consisting of a 283s accreting X-ray pulsar in a close orbit of 8.964 days around the B0.5Ib supergiant HD77581 at a distance…
Variability in high-mass X-ray binaries
F. Fuerst, P. Kretschmar, V. Grinberg +5
Strongly magnetized, accreting neutron stars show periodic and aperiodic variability over a wide range of time scales. By obtaining spectral and timing information on these differe…
Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
L. Decin, W. Homan, T. Danilovich +12
In 1981, the idea of a superwind that ends the life of cool giant stars was proposed. Extreme OH/IR-stars develop superwinds with the highest mass-loss rates known so far, up to a…
