Black hole X-ray binaries sometimes show powerful outflows along the accretion disk, which is called the disk winds. They often appear in X-ray spectra as blueshifted, highly ionized absorption lines. Previous observations suggest that the mass loss rate due to disk winds is comparable to the mass accretion rate onto black holes, and therefore the disk winds are thought to have a significant...
Winds from accretion discs around compact objects, both in X-ray binaries and Active Galactic Nuclei, have been extensively studied in the past two decades with X-ray spectroscopy. However, to date, the launching mechanism of these winds remains a highly controversial topic. A distinct advantage of studying these winds in high inclination, dipping, neutron star X-ray binaries is that highly...
The first year and a half of XRISM science has led to a select number of observations of Black Hole Low Mass X-ray Binaries (BHLMXB), most of which in very unusual states. We will briefly present the context of all these observations, and notably results for :
-A faint soft state exposure of the Black Hole candidate 4U 1630-47 taken at the end of its 2022-2024 outburst. Despite the closest to...
