Abstract Several types of stars present a variable radio emission. In this paper we present a time-dependent model aimed to reproduce the RS CVn emission, which however can be easily extended to other types of stars. The time evolution of a population of electrons following an initial power-law distribution is studied. It is shown that the spectrum of the emitted radiation evolves, in a time scale of a few days, from the typical spectrum of the flaring emission to the flat one observed in quiescent periods. It is also shown that the intensity distribution reproduces the core-halo structure observed using VLBI for a period of about one day after the flare.
