Feasible? Or likely?
Well, informally they're the same thing. "Feasible" does sound better to the ear since I'm crafting the system, however.

This black and purple flora is chemosynthetic, I suppose, as it grows in complete darkness.
Photosynthetic. I was imagining that there would be plenty of UV from the black hole from infalling matter. (Where did the accretion disk come from? I don't know. That's a step further down that I've gotten, yet.) The thylakoids in the chloroplasts would appear black if they absorbed those particular wavelengths.
These inhabitants — how did they survive being inside a supernova? Or did they evolve later on an airless, waterless moon?
Thus hiding the planet / moon behind the jovian. Also accepting that a good portion of the atmo- and hydrospheres would be eliminated. But, only one city of 10,000 would need to survive. (c.f. Toba) I'm also picturing that the planet needs to survive a blast wave and not a prolonged baking, which may be incorrect.
It may be that I'll need to have the black hole be wandering and captured by the system. Which will have unfortunate consequences for the original star.
