Irregular hexahedral dust grains yield nearly the same polarization morphology and fraction as spherical grains in self-scattering regimes but with up to 2.5 times higher scattering opacity, and are still insufficient to match observed polarization levels.

Sustained mass transfer from a circumbinary disc enables giant planet formation in gamma-Cephei-like binaries by prolonging the lifetime of the circumprimary disc against truncation and photoevaporation.
Hydrogen tunneling makes H-abstraction reactions by C2H, OH, and CN competitive in TMC-1 despite low individual rates, affecting aromatic abundance predictions.
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.
Reviews direct imaging of protoplanets and proposes deriving observational estimates of planet mass-to-radius ratio to test formation models, highlighting ELT capabilities.
