GX13+1
Accretion disc winds are clearly seen in black hole and neutron star binaries, but their origin is controversial. Are they magnetically driven, connecting them to the jet as well as to the accretion process itself, or are they thermal/radiative, driven by X-ray irradiation of the outer disc? GX13+1 persistently shows a massive wind in absorption, and is the most reliable LMXRB wind source to address the key question of the origin of the wind. A 30ks Resolve observation can directly measure the wind velocity profile along the line of sight, which will distinguish between magnetic and thermal-radiative acceleration. An additional 80ks observation of 2S0921 will instead shows the wind in emission, as its very high inclination angle means the X-ray source is obscured by the disc.
