Older Upper Scorpius disks show reduced molecular emission and hints of higher inner-gas C/O ratios than young disks, indicating chemical evolution consistent with pebble drift.

JWST/MIRI survey of 2-6 Myr Upper Scorpius disks finds diverse chemotypes, 10-1000x lower water luminosities, and evidence that outer dust traps control inner-disk chemistry.
Observations of the HK Tau binary with JWST reveal gas-phase molecular lines in the low-inclination primary and ice absorption features in the edge-on secondary, enabled by their differing inclinations.
V1094 Sco's disk shows a planet-like double gap at ~100 au and outer rings matching secular gravitational instability, implying a hybrid origin for ring-gap pairs in one disk.
X-Shooter survey of 127 Upper Scorpius disks finds no correlation between accretion rate and disk dust mass or gas radius, with increased dispersion versus younger regions suggesting inner-outer disk decoupling.
N-body simulations show sub-virial fractal star clusters produce more captured asteroids and rogue objects than virialised Plummer clusters, while neither efficiently forms an Oort Cloud.
ALMA observations of 100 Ophiuchus discs show substructures linked to giant planet formation are common in discs above 10 Earth masses of dust and increase from Class I to Class II stages.
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.

A Hybrid Origin for the Multiple Ring-Gap Structures in the Large Protoplanetary Disk V1094 Sco: A Low-Mass Planet and Secular Gravitational Instability
