SUMMARY:From AGB stars to Planetary Nebulae: what the ISM\, stellar rotation\, and companions can do
DESCRIPTION:Asymptotic giant branch (AGB) stars lose their envelopes by means of heavy mass-loss rates. Besides the mass-loss process itself there are other mechanisms that influence the evolution of the star and of what we see as Planetary Nebulae. Among them are the interaction of the ejecta with the interstellar medium (ISM)\, the inclusion of stellar rotation and/or the presence of a companion. I will present our simulation of the interaction process between AGB stars and  the ISM. I will show what we can expect for the planetary nebula formation when we include rotation in stellar evolution models and finally I will describe how these stars are influenced by the presence of external companions
