You probably want to have at least a couple of absorption
and reradiation steps in order not to waste anything.
SiC should be able to work at 800 K, and that would emit
enough to power the high layers of the circumstellar node
cloud. The outer layer could be actually ultra-cold, using
reversible computation, spintronics, QC, and similar.

It would be interesting to see how much orbiting material
you'll need to make it work, and what the total emission
spectrum would be. It would definitely look quite strange,
but unfortunately quite dim.
