@futurebird so - here's a different system that looks like a giant ring that we discovered recently - click through to see the animation! https://kenworthy.space/projects/asassn21js/ I have about three more systems that look as if they have rings in them, but analysis is tricky and slow - so it goes! I'm very fortunate to be able to chase these things up, I think they're fascinating. Thanks for your interest! Cheers, Matt /fin
