Observational evidence for mass-loaded outflows or winds is widespread across the entire astrophysical mass range and most of the electromagnetic spectrum.

Abstract We review two techniques of indirect imaging of accretion discs in cataclysmic variable stars. The light curves of eclipsing systems depend on the distribution of surface brightness over the disc and the eclipse mapping method uses this information to find the continuum surface brightness image of the disc.

Magnetically-controlled disc accretion
Geophysical & Astrophysical Fluid Dynamics, 1992Abstract A magnetic alternative to the viscous accretion disc, around a non-magnetic star, is presented. The disc field is generated by an αω-dynamo; only weak turbulence is required to produce the α-effect, so the viscous force is negligible. The magnetic force does not significantly affect the vertical equilibrium or the radial momentum, hence ...

Highly collimated jets are associated with young stellar objects of all masses. They are also prevalent in microquasars and a variety of active galactic nuclei. Common to all of these systems is the presence of accretion discs around central objects, be they young stars, compact objects, or black holes.

The amount of literature on accretion discs is now vast and growing. Accretion discs (and here I include all thin, centrifugally supported discs, whether gaseous or not) can be found in a wide range of astrophysical models including planetary rings, the presolar nebular, star formation, binary stars, galaxies and active galactic nuclei.

Accretion Discs in Astrophysics
Annual Review of Astronomy and Astrophysics, 1981If we put a particle in a circular orbit around a central gravitating body, it will stay in that orbit. If we then extract energy and angular momentum from the particle we may allow it to spiral slowly inwards. The amount of energy that can be extracted by such a process is equal to the binding energy of the innermost accessible orbit.

Abstract Based on large amount of observational data in the field of high energy astrophysics, and namely X- and Gamma-ray data, it is considered that most of the discrete sources are non-stationary. One of the mechanisms describing this phenomenon is the non-stationary disc accretion, of geometrically thin disc.
