Intent

We intend to investigate the dependence of the observed properties of (black hole/neutron star) X-ray binary systems on their orbital inclination, and the inflow/outflow coupling in accreting systems. We will address the following major questions: which properties of accreting X-ray binaries are inclination-dependent (e.g. related to the jet and inner accretion flow emission)? can we unify any of the observed phenomenology by considering the inclination dependence? what can the inclination-dependence of X-ray absorption lines/radio jet emission tell us about the geometry of the disc winds/the jet Lorentz factors? are these properties constant with time, or do they evolve throughout the different spectral-timing states of an outburst? Answering these fundamental questions requires a multi-wavelength approach as well as the development of improved theoretical models.
