Photometry of outer Solar System objects from the Dark Energy Survey II: a joint analysis of trans-Neptunian absolute magnitudes, colors, lightcurves and dynamics
For the 696 trans-Neptunian objects (TNOs) with absolute magnitudes $5.5 < H_r < 8.2$ detected in the Dark Energy Survey (DES), we characterize the relationships between their dynamical state and phys...

Cool thread with one of my favorite plots of all time!
Well... the discussion around 3I/ATLAS continues to... evolve. This object is super exciting, fascinating, worthy of a LOT of study and press! ALSO so far as I have seen, & from every solar system expert I've talked to (and I know a lot of 'em!), it looks like a comet, not a spaceship.
