Pulse profiles of tall accretion columns in X-ray pulsars
Bagration Megrelishvili, Pavel Abolmasov
Accreting X-ray pulsars (XRPs) are strongly magnetized neutron stars (NSs) distinguished by a periodic variability pattern related to the rotation of their magnetospheres (pulsatio…
Variable opacity and accretion-column regimes of magnetized neutron stars
Galina Lipunova, Pavel Abolmasov
Radiation-supported accretion columns of magnetized neutron stars can operate in several distinct regimes. As the accretion rate increases, magnetospheric accretion may proceed thr…
Shock-free super-Eddington accretion onto magnetized neutron star
Galina Lipunova, Pavel Abolmasov
Strong magnetic fields allow accreting neutron stars to form magnetically controlled funnel flows. At sufficiently high accretion rates, such flows become radiation-pressure-suppor…
Numerical approach to compressible shallow-water dynamics of neutron-star spreading layers
Aleksandr Rusakov, Pavel Abolmasov, Omer Bromberg
A weakly magnetized neutron star (NS) undergoing disk accretion should release about a half of its power in a compact region known as the accretion boundary layer. Latitudinal spre…
Interface instabilities in hydrodynamic relativistic jets
Pavel Abolmasov, Omer Bromberg
Both the dynamics and the observational properties of relativistic jets are determined by their interaction with the ambient medium. A crucial role is played by the contact discont…
Simulating the shock dynamics of a neutron star accretion column
Pavel Abolmasov, Galina Lipunova
Accretion onto a highly-magnetised neutron star runs through a magnetospheric flow, where the plasma follows the magnetic field lines in the force-free regime. The flow entering th…
