Microquasars are Galactic black hole systems in which matter is transferred from a donor\nstar and accretes onto a black hole of, typically, 10ââ?¬â??20 solar masses. The presence of an accretion disk\nand a relativistic jet made them a scaled down analogue of quasarsââ?¬â?thence their name. Microquasars\nfeature prominently in the scientific goals of X-ray polarimeters, because a number of open questions,\nwhich are discussed in this paper, can potentially be answered: the geometry of the hot corona\nbelieved to be responsible for the hard X-ray emission; the role of the jet; the spin of the black hole.
