First Adiabatic Invariant and the Brightness Temperature of Relativistic Jets
Assuming that the first adiabatic invariant for radiating particles in relativistic jets is conserved, we investigate the change in brightness temperature along the jet axis. We show that in this case the observed break in the dependence of the brightness temperature on the distance to the ‘‘central engine’’ can be explained.
