Abstract

In this talk I shall review the current state of the art in our empirical understanding between the properties of accretion flows around (stellar mass) black holes and two different forms of outflow, namely winds and jets. This includes new analyses based not only on X-ray colours, but also variability properties and X-ray reflection. I will showcase new work which shows that neutron stars behave just like the black holes in nearly all respects, and will discuss the integrated feedback of kinetic energy, momentum and mass over the course of the evolution of such sources.
