Magnetospheric flows in X-ray pulsars II: Heating, cooling and ionization degree at sub-critical accretion
Alexander A. Mushtukov, Alexander Y. Potekhin, Valery F. Suleimanov +2
Magnetospheric accretion flows in X-ray pulsars shape their spectra, polarization, and variability. We model the thermal balance of the flow enveloping the neutron star magnetosphe…
Neutron contribution to the force on a proton vortex in superconducting neutron-star matter
Oleg A. Goglichidze, Mikhail E. Gusakov
We investigate the forces acting on a proton vortex in superconducting neutron-star matter composed of neutrons, protons, and electrons, accounting for Fermi-liquid interactions in…
Numerical model of fast electron energy deposition in interstellar molecular gas
Aleksandr Nesterenok
The energy deposition of fast electrons in interstellar molecular gas is considered. We use the rotationally resolved cross sections for electron-impact excitation of H molecul…
Vacuum polarization and cyclotron resonance effects on radiative transfer and plasma deceleration in subcritical X-ray pulsars
I. D. Markozov, A. Y. Potekhin, A. D. Kaminker +1
We investigate the spectrum and polarization of radiation emerging from a subcritical X-ray pulsar using self-consistent radiation-hydrodynamic simulations of an accretion channel…
Direct simulations of very high energy cosmic ray acceleration in 3D MHD model of a compact star cluster
M. E. Kalyashova, A. M. Bykov, D. V. Badmaev
Young compact clusters of massive stars contain dozens of O-, B- and WR-type stars with fast powerful winds in a small pc radius core. The particle acceleration by ensembles…
Nature of 4FGL J2249.4+6229: Evidence for a redback system with a cool companion and low X-ray and -ray luminosities
A. V. Karpova, D. A. Zyuzin, S. V. Zharikov +1
We report the identification of the likely X-ray and optical counterpart to the unassociated Fermi source 4FGL J2249.4+6229. To clarify its nature, we investigate the X-ray data fr…
