Point-symmetry and the double planetary nebula KJPN 8

open access: yes, 2002
We present recent results of two topical problems on dynamical evolution of Planetary Nebulae (PNe) where binary nuclei, stellar rotation and magnetic elds play relevant roles. Namely, point-symmetry and multiple, collimated outflows.

X-rays from planetary nebulae: Unveiling wind collisions and binarity

open access: yes, 2010
Planetary nebulae (PNe), the ionized, ejected envelopes of low- to intermediate-mass stars, are thought to be shaped by a nascent fast wind from the spent core (a future white dwarf) that collides with and sweeps up previously ejected material (red and ...

The Evolution of Planetary Nebula Nuclei

open access: yes, 1985
The evolution of planetary nebula nuclei (PNNs) is examined with the aid of the most recent available stellar evolution calculations and new observations of these objects.
