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…
The low luminosity end of Galactic HMXBs with eROSITA: Establishing a luminosity floor for accreting BeXRBs
Aafia Zainab, Philipp Thalhammer, Nico Zalot +18
We present a first look at the Galactic population of heretofore known HMXBs as observed by SRG/eROSITA during its first four surveys. eROSITA's sensitivity of $\sim10^{-13}\,\math…
A simple relation: Neutron star magnetic field strength and spectral shape at low mass accretion rates
Nicolas Zalot, Ekaterina Sokolova-Lapa, Aafia Zainab +8
The X-ray spectra of neutron stars with moderate magnetic fields ( G) in high-mass X-ray binaries (HMXBs) at low X-ray luminosities ( e…
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…
Double-hump spectrum, pulse profile dip, and pulsed fraction spectra from the low-accretion regime in the X-ray pulsar MAXI J0655-013
C. Malacaria, S. N. Pike, A. D'Aì +18
Accreting X-ray pulsars (XRPs) undergo different physical regimes depending on the mass accretion rate. Recent observations have shown a dramatic change in the emission properties…
Don't torque like that. Measuring compact object magnetic fields with analytic torque models
J. J. R. Stierhof, E. Sokolova-Lapa, K. Berger +10
Context. Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-s…
Multiwavelength study of 1eRASS J085039.9-421151 with eROSITA NuSTAR and X-shooter
Aafia Zainab, Artur Avakyan, Victor Doroshenko +23
The eROSITA instrument on board Spectrum-Roentgen-Gamma has completed four scans of the X-ray sky, leading to the detection of almost one million X-ray sources in eRASS1 only, incl…
An in-depth analysis of the variable cyclotron lines in GX 3012
Nicolas Zalot, Ekaterina Sokolova-Lapa, Jakob Stierhof +13
Context. The High-Mass X-ray Binary (HMXB) system GX 3012 is a persistent source with a well-known variable cyclotron line centered at 35 keV. Recently, a second cyclotron line…
