Accreting on the edge: a luminosity-dependent cyclotron line in the Be/X-ray Binary 2S 1553-542 accompanied by accretion regimes transition

Christian Malacaria, Yash Bhargava, Joel B. Coley +15

Accreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the luminosity-dependent spectral and timing features of the neutron star's emission can be analyzed in…

X-ray emission from magnetized neutron star atmospheres at low mass accretion rates. I. Phase-averaged spectrum

E. Sokolova-Lapa, M. Gornostaev, J. Wilms +12

Recent observations of X-ray pulsars at low luminosities allow, for the first time, to compare theoretical models for the emission from highly magnetized neutron star atmospheres a…

NuSTAR observation of GRO J1744-28 at low mass accretion rate

O. König, F. Fürst, P. Kretschmar +8

We present the spectral analysis of the LMXB GRO J1744-28 using 29 ks of NuSTAR data taken in 2017 February at a low luminosity of erg/s (3-50 keV). The c…

High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen

M. A. Leutenegger, S. Kühn, P. Micke +25

We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…

The giant outburst of 4U 0115+634 in 2011 with Suzaku and RXTE

Matthias Bissinger né Kühnel, Ingo Kreykenbohm, Carlo Ferrigno +19

We present an analysis of X-ray spectra of the high mass X-ray binary 4U 0115+634 as observed with Suzaku and RXTE in 2011 July, during the fading phase of a giant X-ray outburst.…

Chandra X-ray spectroscopy of the focused wind in the Cygnus X-1 system III. Dipping in the low/hard state

Maria Hirsch, Natalie Hell, Victoria Grinberg +9

We present an analysis of three Chandra High Energy Transmission Gratings observations of the black hole binary Cyg X-1/HDE 226868 at different orbital phases. The stellar wind tha…
