Point-symmetry and the double planetary nebula KJPN 8
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
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 ...
