| Abstract | We propose a high-resolution spectral study of the transient black hole X-raybinary MAXI J1810-222, to clearly resolve and determine the nature of one of themost powerful and fastest wind ever observed in a Galactic accreting system. Werequest a 60 ks XMM-Newton observation when the source is either in soft orintermediate state to constrain the physical parameters of the wind with muchgreater accuracy than those derived from the available NICER spectra. Byanalysing these spectra, we obtained evidence for a spectral-state dependentoutflow, with mildly relativistic speed, which would test current theoreticalmodels of winds formation in X-ray binaries. RGS is the only instrument able toresolve sharp features around 1 keV within our observing constraints. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
