A new grid of disk models with grain-surface CO chemistry plus an ML inference tool produces gas mass estimates from ALMA observations that match independent dynamical and HD values without requiring extreme elemental depletion.
Uranus and Neptune are reinterpreted as magma-ocean giants with hydrogen-rich interiors rather than traditional ice giants, consistent with observations via three fit parameters each.
Microlensing-inferred free-floating planets plus bound planets require more mass than protoplanetary disks supply, even at 100% conversion efficiency, potentially creating a crisis if the mass function is bottom-heavy.
Halos in Elias 2-24, IM Lup, and DM Tau hold 20-30% of total dust mass with cm-sized grains, helping resolve the disk mass-budget problem even though drift and growth timescales are shorter than disk ages.
Ionization rates in the envelopes of NGC-1333 IRAS4A, L1448-C, and L1157 reach 1e-16 to 1e-13 s^{-1}, far above the ISM baseline of 6e-17 s^{-1}.
