Great similarities between the objects M 1-92, a proto planetary nebula of bipolar morphology, and MWC 560, a symbiotic star with a jet, have been found. A brief review of the previous studies for both objects is presented for the purpose of proposing mechanisms that best explain this similarity, since up to now, both objects have been studied independently.
From the comparison of the spectra of both objects, the existence of a jet is confirmed spectroscopically for the young planetary nebula M 1-92, as well as its binary nature and the existence of a circumnuclear disk. Finally an evolutionary sequence is proposed for the two objects, where M 1-92 corresponds to a more advanced evolutionary stage with an estimated difference of 900 years.
