A tiny planetary in Puppis

[Atmos (Colin)]

The typical white dwarf when “created” is going to be around 200,000K but because it doesn’t create any of its own energy (no longer undergoes nuclear fusion), it’ll just slowly cool down.

As most planetary nebula dispurse in 10,000-50,000 years, one could argue that most white dwarfs seen with an associated planetary Nebula should be of approximately the same temperature.

That is interesting about the temperature because I also read the same but then when I imaged the butterfly nebula or bug nebula I read this also had a surface temperature of 200,000K. I do wonder which one is the hotter of the two.

I probably should have said "one of the hottest" although I seem to remember a visiting speaker at a society meeting saying it was the hottest then known

Saw this one through my 16" dob last night. The seeing was pretty poor, but you could definitely detect its non-spherical nature. I couldn't detect any significant details or colours, sadly.

Thanks guys for comments and thanks for the clarifications Colin.
