Resumen: The decay of charged pions produced in proton-proton collisions between stellar wind ions and relativistic protons in microquasar (MQ) jets can generate secondary leptons that emit through detectable synchrotron radio emission. Energy losses due to synchrotron and inverse Compton (IC) processes, and adiabatic expansion are taken into account. We present a model to compute the synchrotron emission using particle energy distributions that are consistently derived. We present the Spectral Energy Distributions (SEDs) while exploring the space parameter in our model. Our conclusions show a significant though hardly dominant contribution of secondary leptonic emission to the total radio emission. On the other hand, observational consequences obtained can be used to test some still unknown processes occurring in these objects as well as the nature of the matter outflowing in their jets.
