ate helium flash in V605 Aql: PNe evolution and shell formation in quick motion

Abstract

The "born-again" PNe V605 Aql (A58) and V4344 Sgr (Sakurai) give us the rare chance to follow shell formation and building of the winds in "real-time". The high carbon abundance, and thus the high dust formation rate, enhances the mechanisms. Thus the timescales are shortened. My data presented here gives a quick look on the results of new observations of V605 Aql and its old planetary nebula (PN) A58 obtained at the ESO NTT (August 2002).
