Abstract

The image quality achievable with modern telescopes (from the space but also from the ground) allows the apparent growth of relatively close/fast stellar outflows to be revelaed and measured in timescales of few years. The information about the tangential component of the gas and shocks motions, coupled with line-of-sight velocities from Doppler shifts, allows a detailed view of the dynamical evolution of the outflows to be obtained, a privileged information for theoretical modelling.

In this "live" poster, animations that we have obtained by combining multi-epoch images of several outflows from evolved stars will be displayed on a computer screen. They include the lighthouse rotation of the "symbiotic" planetary nebula M2-9, the ballistic expansion of the classical nova remnant (surrounded by an old PN) in GK Per, the equatorial-and-polar fast outflows from the symbiotic stars R Aqr, Hen 2-147 and Hen 2-104, and the shaping at work in the proto-PNe CRL618 and CRL2688 and in more mature PNe such as NGC 6543.
