The Ecology of Rotators

A generalized physical object, a gravimagnetic rotator (or simply, rotator), is considered. It is specified by the three characteristics: a mass, a magnetic field, and an angular momentum. A rotator interacts with its environment (plasma) via two kinds of the physical fields, the electromagnetic and the gravitational ones. This rotator is a useful theoretical consideration for quite different astrophysical objects: neutron stars, white dwarfs, magnetic stars, super-mass stars (spinars), etc. The ecology of rotators involves the classification of rotators concerning their interaction with the environment, determination of the evolutionary laws and their energetic interpretation, the analysis of stochastic fluctuations, and statistical description of evolution of rotator ensemble. These problems resemble those considered in synergetics. Possible implications for some particular astronomical objects are briefly described: X-ray and radiopulsars, single white dwarfs, X-ray bursters, cataclysmic variables, magnetic stars, active galactic nuclei, and quasars. A number of self-similar solutions are derived.
