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. DÃaz 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…
