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…
High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen
M. A. Leutenegger, S. Kühn, P. Micke +25
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…
