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…
Continuum, cyclotron line, and absorption variability in the high-mass X-ray binary Vela X-1
C. M. Diez, V. Grinberg, F. Fürst +7
Because of its complex clumpy wind, prominent cyclotron resonant scattering features, intrinsic variability and convenient physical parameters (close distance, high inclination, sm…
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…
Accurate Treatment of Comptonization in X-ray Illuminated Accretion Disks
Javier A. García, Ekaterina Sokolova-Lapa, Thomas Dauser +5
A large fraction of accreting black hole and neutron stars systems present clear evidence of the reprocessing of X-rays in the atmosphere of an optically-thick accretion disk. The…
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.…
