A dynamical model for FR II type radio sources with terminated jet activity.

KULIGOWSKA E.

Abstract (from CDS):

Context. The extension of the KDA analytical model of FR II-type source evolution originally assuming a continuum injection process in the jet-IGM interaction towards a case of the jet's termination is presented and briefly discussed.
Aims. The dynamical evolution of FR II-type sources predicted with this extended model, hereafter referred to as KDA EXT, and its application to the chosen radio sources.
Methods. Following the classical approach based on the source's continuous injection and self-similarity, I propose the effective formulae describing the length and luminosity evolution of the lobes during an absence of the jet flow, and present the resulting diagrams for the characteristics mentioned.
Results. Using an algorithm based on the numerical integration of a modified formula for jet power, the KDA EXT model is fitted to three radio galaxies. Their predicted spectra are then compared to the observed spectra, proving that these fits are better than the best spectral fit provided by the original KDA model of the FR II-type sources dynamical evolution.
