Accretion form a clumpy massive-star wind in Supergiant X-ray binaries
I. El Mellah, J. O. Sundqvist, R. Keppens
Supergiant X-ray Binaries (SgXB) host a compact object, often a neutron star (NS), orbiting an evolved O/B star. Mass transfer proceeds through the intense line-driven wind of the…
The clumpy absorber in the high-mass X-ray binary Vela X-1
V. Grinberg, N. Hell, I. El Mellah +13
Bright and eclipsing, the high-mass X-ray binary Vela X-1 offers a unique opportunity to study accretion onto a neutron star from clumpy winds of O/B stars and to disentangle the c…
MPI-AMRVAC 2.0 for Solar and Astrophysical Applications
C. Xia, J. Teunissen, I. El Mellah +2
We report on the development of MPI-AMRVAC version 2.0, which is an open-source framework for parallel, grid-adaptive simulations of hydrodynamic and magnetohydrodynamic (MHD) astr…
Wind accretion onto compact objects
Ileyk El Mellah
X-ray emission associated to accretion onto compact objects displays important levels of photometric and spectroscopic time-variability. When the accretor orbits a Supergiant star,…
