Probing the disc wind-jet connection in black hole transients 2

We propose 4 observations of one high inclination black hole low mass X-ray binary (LMXB) at different stages of its outburst. We will investigate the presence of X-ray narrow absorption/emission features in the XMM spectra, which are a signature of a disc wind, and their relation to the accreting regime. Such features, identified with ions like FeXXV and FeXXVI, have been observed in a number of LMXBs and give us information about the mass outflow rate and the launching mechanism of the wind. With simultaneous radio observations we will probe the jet power as a function of the wind properties and how the radio flux density correlates with the X-ray flux at different accretion regimes. We will also investigate the broadening mechanism of the FeK emission line detected up to now in several LMXBs.
