IGR_J17062-6143
IGR J17062-6143 habors a neutron star that spins at 163~Hz and is in a 38-min orbit with a hydrogen-deficient companion star. Previous Chandra/HETG and XMM-Newton/RGS observations revealed hints of blue-shifted spectral lines at <2 keV energies that could indicate the presence of an outflowing wind. Since the commonly inferred thermal wind-launch mechanism cannot operate in such a very compact binary, the putative wind may be launched by magnetic processes. XRISM can reveal if a wind is indeed present by now allowing to search for narrow lines from a wind in the 6-7 keV Fe-K band. If confirmed, it would be the first undisputed detection of a magnetic wind in an X-ray binary and would have broad astrophysical implications.
