Stingray Nebula

I have a weird obsession with this PN for some reason. To fuel that, here's a recent paper from ArXiv on it. You may find this interesting.

Good luck figuring it out. I'm still boggling over the Red Rectangle.
Just call me "geck" because "zilla" is like a last name.

Yes, this paper made me understand what happened to the star a lot better. It was an ordinary post-AGB protoplanetary and then suddenly, around 1980, bam! It's emission lines transformed to a planetary nebula suddenly. This gave an opportunity to watch the ionization of a post-AGB protoplanetary shell to a full-fledged planetary nebula. Very exciting and interesting case.
