J/A+A/281/15 J/A+A/281/15 The asymmetries in radio source structures. I. S Rys Astron. Astrophys. 281 15 1994 1994A&A...281...15R galaxies: active quasars: general radio continuum: galaxies A method is suggested for the mathematical description of the asymmetry occurring in the radio-source structures. The method is based on the transformation of the radio structure into 'itself' and may be used for all morphological types of structures. Two models of generation of the source asymmetry are investigated, namely Doppler effects and the flip-flop mechanism, with an assumption that the luminosity of the plasma volume depends on time as a power law S approximately t(exp mu). The model with Doppler effects turns out to be more suitable than that with flip-flop mechanism.
