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…

XMM-Newton Observations of Flares and a Possible Pulse Dropout in the Supergiant X-ray binary 4U 1909+07

Joel B. Coley, Ralf Ballhausen, McKinley Brumback +9

We report on a pair of X-ray Multi-Mirror Mission (XMM-Newton) observations of the Supergiant X-ray binary 4U 1909+07, which were performed on 2021 October 3 and 2021 October 8, re…

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…

Detection of the orbital modulation of Fe K fluorescence emission in Centaurus X-3 using the high-resolution spectrometer Resolve onboard XRISM

Yuto Mochizuki, Masahiro Tsujimoto, Richard L. Kelley +9

The Fe K fluorescence line emission in X-ray spectra is a powerful diagnostic tool for various astrophysical objects to reveal the distribution of cold matter around photo-ioniz…
