The unifying scheme contains two large groups of exact MHD outflow models: (I) meridionally self-similar models with spherical critical surfaces; and (II) radially self-similar models with conical critical surfaces. This classification includes known polytropic models, such as the classical Parker description of a stellar wind and the Blandford &amp;amp;38 Payne model of a disc wind; it also contains non-polytropic models, such as those of winds/jets in Sauty &amp;amp;38 Tsinganos, Lima, Tsinganos &amp;amp;38 Priest, and Trussoni, Tsinganos &amp;amp;38 Sauty. Besides the unification of all known cases under a common scheme, several new classes emerge and some are briefly analysed; they could be explored for a further understanding of the physical properties of MHD outflows from various magnetized and rotating astrophysical objects in stellar or galactic systems.</style></abstract></record></records></xml>
