4U 1538-52 in a Heartbeat: Broadband X-ray Spectral Properties from XMM-Newton and NuSTAR

C. M. Diez, S. Dupourqué, A. -L. Doherty +8

Galactic high-mass X-ray binaries (HMXBs) are important systems for studying accretion mechanisms onto compact objects and for investigating the complex stellar winds of massive st…

Pulse profile variations in the accreting X-ray pulsar Vela X-1

V. Madurga-Favieres, A. Martin-Carrillo, C. M. Diez +7

Vela X-1 is a well-studied accreting X-ray pulsar, with a distinctive pulse profile that has been found to be very similar in different observations spread out over decades. On the…

Low-frequency spectra of neutron star + OB supergiant binaries: Does wind density drive persistent and flaring modes of accretion?

J. van den Eijnden, L. Sidoli, M. Díaz Trigo +10

Neutron star high-mass X-ray binaries are well-studied in wavebands between the infrared and hard X-rays. Their low-frequency millimeter and radio properties, on the other hand, re…

Variable structures in the stellar wind of the HMXB Vela X-1

L. Abalo, P. Kretschmar, F. Fürst +9

Strong stellar winds are an important feature in wind-accreting high-mass X-ray binary (HMXB) systems, providing insights into stellar evolution and their impact on surrounding env…

The first mm detection of a neutron star high-mass X-ray binary

J. van den Eijnden, L. Sidoli, M. Diaz Trigo +9

Neutron stars accreting from OB supergiants are often divided between persistently and transiently accreting systems, called Supergiant X-ray Binaries (SgXBs) and Supergiant Fast X…

Observing the onset of the accretion wake in Vela X-1

C. M. Diez, V. Grinberg, F. Fürst +7

High-Mass X-ray Binaries (HMXBs) offer a unique opportunity for the investigation of accretion onto compact objects and of wind structure in massive stars. A key source for such st…

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…

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…
