Looking through the photoionisation wake: Vela X-1 at with Chandra/HETG
R. Amato, V. Grinberg, N. Hell +6
The Supergiant X-ray binary Vela X-1 represents one of the best astrophysical sources to investigate the wind environment of a O/B star irradiated by an accreting neutron star. Pre…
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…
Color-color diagrams as tools for assessment of the variable absorption in high mass X-ray binaries
V. Grinberg, M. A. Nowak, N. Hell
High mass X-ray binaries hold the promise of giving us understanding of the structure of the winds of their supermassive companion stars by using the emission from the compact obje…
High-resolution X-ray spectroscopy of the stellar wind in Vela X-1 during a flare
M. Lomaeva, V. Grinberg, M. Guainazzi +8
We present a 130 ks observation of the prototypical wind-accreting, high-mass X-ray binary Vela X-1 collected with XMM-Newton at orbital phases between 0.12 and 0.28. A stron…
X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years
Maria Hirsch, Katja Pottschmidt, David M. Smith +12
We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…
Chandra X-ray spectroscopy of the focused wind in the Cygnus X-1 system III. Dipping in the low/hard state
Maria Hirsch, Natalie Hell, Victoria Grinberg +9
We present an analysis of three Chandra High Energy Transmission Gratings observations of the black hole binary Cyg X-1/HDE 226868 at different orbital phases. The stellar wind tha…
