Talk:3103: Exoplanet System

"Faint dust cloud that will cause several papers to be retracted" could refer to either Fomalhaut b (former proposed exoplanet that turned out to be a dust cloud) or Tabby's Star (star with odd irregular dimming pattern likely due to a dust cloud, but was briefly thought by some to be an alien megastructure the speculation of which caused the media to lose their shit).

Somebody should word it better but the idea of a black hole accretion disk having a habitable zone is pretty typical for Randall brand humor. 130.76.187.35 20:12, 16 June 2025 (UTC)

I think it's actually a reference to Interstellar. In that movie three planets are sort of in the habitable zone of a giant black hole's accretion disk. Whether that means they have to be in the accretion disk, or whether they can be outside it but still in the habitable zone of the disk's radiation, I'm not sure. -- Ken g6 (talk) 00:17, 17 June 2025 (UTC)

An alternative reading of #18 is that the planet may or may not be too hot for rocks to solidify at the surface. (Even if this turns out to be implausible, Randall does stretch the bounds of plausibility on occasion.) 87.75.45.216 08:36, 17 June 2025 (UTC)

An accretion disk is also found around a star. So the exoplanet may be in the zone where planets may actually form. (talking about the title text) 129.27.217.99 08:59, 17 June 2025 (UTC)

An accretion disk forms around my desk. Whether or not it counts as habitable is debatable, though. 82.13.184.33 09:15, 17 June 2025 (UTC)

Yeah, the Earth is thought to have formed from the accretion disk of the Sun 4.5b years ago. It probably has nothing to do with black holes. Robisodd (talk) 12:12, 17 June 2025 (UTC)
