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…
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…
