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.

N-body simulations find stellar mass-loss effects dominate gravitational scattering in altering giant planet orbits around white dwarfs formed in star clusters, independent of density and initial conditions.
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.
