How the spin-phase variability of cyclotron lines shapes the pulsed fraction spectra: insights from 4U 1538-52
Dimitrios K. Maniadakis, Ekaterina Sokolova-Lapa, Antonino D'Aì +15
We study the energy-dependent pulse profile of 4U 1538-52 and its phase-dependent spectral variability, with emphasis on the behavior around the cyclotron resonant scattering featu…
Energy-resolved pulse profile changes in V 0332+53: Indications of wings in the cyclotron absorption line profile
Antonino D'Aì, Dimitrios K. Maniadakis, Carlo Ferrigno +15
We aim to investigate the energy-resolved pulse profile changes of the accreting X-ray pulsar V 0332+53, focusing in the cyclotron line energy range, using the full set of availabl…
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…
Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415
Pragati Pradhan, Carlo Ferrigno, Biswajit Paul +11
Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object ca…
Fitting strategies of accretion column models and application to the broadband spectrum of Cen X-3
Philipp Thalhammer, Matthias Bissinger, Ralf Ballhausen +10
Due to the complexity of modeling the radiative transfer inside the accretion columns of neutron star binaries, their X-ray spectra are still commonly described with phenomenologic…
Revisiting the archetypical wind accretor Vela X-1 in depth -- A case study of a well-known X-ray binary and the limits of our knowledge
Peter Kretschmar, Ileyk El Mellah, Silvia Martínez-Núñez +9
Context: Vela X-1 is one of the best studied X-ray binaries. Frequently though, specific values for its parameters have been used in subsequent studies without considering alternat…
