A ~2.5 Myr ago passage of HD 7977 within 6000-10000 au can reproduce the observed isotropy in new LPC ω and match returning LPCs, implying doubled current flux and halved Oort cloud population.

Reports asymmetric heliocentric activity slopes for 103P/Hartley 2 and exponential outburst decay plus flattening phase curves for Chiron from ATLAS, ZTF, and LCO photometry.
H-type objects in IC348 show spatial distributions matching stars and brown dwarfs, unlike the more dispersed distribution of simulated ejected planets, indicating a star-like formation origin.

Planet or brown dwarf? Constraints on the formation of H-type objects in IC348
H-type objects in IC348 show spatial distributions matching stars and brown dwarfs, unlike the more dispersed distribution of simulated ejected planets, indicating a star-like formation origin.
