our stellar cousins

[adelaidesean]

I started off the day reading this interesting article about the discovery of "carbon stars"--ancient white dwarfs with atmospheres almost entirely composed of carbon. They're rare, and they challenge our understanding of stellar evolution, and they're bound to end up in a space opera novel before long.

"The great mystery is why these carbon-atmosphere stars are found only between about 18,000 degrees and 23,000 degrees Kelvin. 'These stars are too hot to be explained by the standard convective dredge-up scenario, so there must be another explanation,' Dufour said."

The explanation, of course, is that they're alive.

LOL.

Of course they are! Active "hot" carbon superstructures.

They're late model Matrioshka Brains (http://en.wikipedia.org/wiki/Matrioshka_brain) running on hot cycle systems.

Or they're built.

But why? What would need to operate at those temperatures? I guess it's time to start looking at what's orbiting them...

After all, they're too small and too hot to be Dyson spheres, even loose ones like Matrioshkas...

Yes! And they're laughing at us for not realising sooner. Making LOLhumans, perhaps. :-)

Alive, built...or dead and rotting? That's a deliciously gothic notion, now it occurs to me. Hmm.

Maybe the stars are stellar graveyards, where they've dumped all their organic crap.

What could a carbon star provide an advanced civilisation that an ordinary white dwarf couldn't?

Maybe they're furnaces for buckyballs and nanotubes by the gazillions.

Obviously they're really just planets where carbon-dioxide-based global warming has really gotten out of control.

*Seriously* out of control, if it turns them into suns!

I love this idea. It almost makes global warming seem, well, cool.

PS. I love the way the eyes move on your icon, but never when I'm looking right at it. Spooky. :-)
