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…

High resolution X-ray spectroscopy of Supergiant HMXB 4U170037 during the compact object eclipse

M. Martínez-Chicharro, V. Grinberg, J. M. Torrejón +6

We present an analysis of the first observation of the iconic High Mass X-ray Binary \so with the \chandra High Energy Transmission Gratings during an X-ray eclipse. The goal of th…

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.…

Evidence of Compton cooling during an X-ray flare supports a neutron star nature of the compact object in 4U1700-37

M. Martinez-Chicharro, J. M. Torrejón, L. Oskinova +5

Based on new Chandra X-ray telescope data, we present empirical evidence of plasma Compton cooling during a flare in the non pulsating massive X-ray binary 4U1700-37. This behaviou…

A precessing Be disk as a possible model for occultation events in GX 304-1

Matthias Kühnel, Richard E. Rothschild, Atsuo T. Okazaki +14

We report on the RXTE detection of a sudden increase in the absorption column density, , during the 2011 May outburst of GX 304-1. The increased up to…

Low-luminosity stellar wind accretion onto neutron stars in HMXBs

Konstantin Postnov, Lida Oskinova, Jose Miguel Torrejón

Features and applications of quasi-spherical settling accretion onto rotating magnetized neutron stars in high-mass X-ray binaries are discussed. The settling accretion occurs in w…
