Pulse profiles of accreting neutron stars - A review of analysis methods, observations, and theoretical models
Katja Pottschmidt, Peter Kretschmar, Ekaterina Sokolova-Lapa +25
X-ray pulsars are highly magnetized ( G) neutron stars accreting from a donor star. Their characteristic X-ray emission arises from accreted material decelerated fro…
Flux variability of the "10 keV feature" of 4U 0115+63
Katrin Berger, Ekaterina Sokolova-Lapa, Ralf Ballhausen +14
X-ray spectra of accretion-powered X-ray pulsars can often be described using a power-law continuum with a high-energy cutoff, which might be further modified by additional spectra…
Theoretical Analysis of the RX J0209.6-7427 X-ray Spectrum During Giant Outburst
Brent F. West, Peter A. Becker, Georgios Vasilopoulos
We model the spectral formation occurring in the binary X-ray pulsar RX~J0209.6-7427 during the 2019 super-Eddington outburst. Using a theoretical model previously developed by the…
The Physics of Accretion Onto Highly Magnetized Neutron Stars
Michael T. Wolff, Peter A. Becker, Joel Coley +16
Studying the physical processes occurring in the region just above the magnetic poles of strongly magnetized, accreting binary neutron stars is essential to our understanding of st…
A New Two-Fluid Radiation-Hydrodynamical Model for X-ray Pulsar Accretion Columns
Brent F. West, Kenneth D. Wolfram, Peter A. Becker
Previous research centered on the hydrodynamics in X-ray pulsar accretion columns has largely focused on the single-fluid model, in which the super-Eddington luminosity inside the…
Dynamical and Radiative Properties of X-ray Pulsar Accretion Columns: Phase-Averaged Spectra
Brent F. West, Kenneth D. Wolfram, Peter A. Becker
The availability of the unprecedented spectral resolution provided by modern X-ray observatories is opening up new areas for study involving the coupled formation of the continuum…
