Descripción
We present our long-term monitoring, using both ground-based telescopes
and the HST, of the expansion in the plane of the sky of the outflows
from evolved stars. They include the PN M2-9 (suspected of hosting a
symbiotic nucleus), the classical nova remnant GK Per, the symbiotic
Miras R Aqr, Hen 2-147 and Hen 2-104, and the proto-PNe CRL 618, CRL
2688, and Hen 3-1475.
