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…
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…
Beaming of polarized radiation in subcritical X-ray pulsars
I. D. Markozov, A. Y. Potekhin, A. D. Kaminker +1
Radiation of X-ray pulsars is powered by accretion on the neutron star surface from a binary companion under the influence of a strong magnetic field. We study beaming of this radi…
Neutron star cooling implications and magnetic field of the Vela Junior central compact object from all XMM-Newton and Chandra spectra
Wynn C. G. Ho, Esther Simkhayeva, Alexander Y. Potekhin
The central compact object (CCO) in the Vela Junior supernova remnant is a young neutron star whose relatively low X-ray flux and small distance suggest it has a mass high enough t…
Neutrino beaming in ultraluminous X-ray pulsars as a result of gravitational lensing by neutron stars
Alexander A. Mushtukov, Alexander Y. Potekhin, Ivan D. Markozov +6
X-ray pulsars experiencing extreme mass accretion rates can produce neutrino emission in the MeV energy band. Neutrinos in these systems are emitted in close proximity to the stell…
