Gas giants form sub-snowline in binaries via dust traps at the tidal truncation radius, with observed planet semi-major axes following a_planet = 0.569 r_t (R²=0.94).
A semi-analytic model using elastoplastic contact mechanics and weakest-link fracture statistics reproduces the sticking-bouncing boundary from DEM simulations and places the bouncing barrier within ALMA-inferred size-velocity ranges for moderately porous aggregates.
Simulations of hypervelocity rocky-on-icy impacts show porosity controls crater morphology but not the efficient vaporization of the rocky impactor material.
Updated DALI models reproduce observed C2H2 fluxes with solar C/O and find the C2H2/H2O flux ratio sensitive to elemental abundances and small-grain abundance in planet-forming disk regions.
Radiative-transfer simulations with common dust models generate a range of spectral indices but cannot reach the lowest observed emissivity indices in protostars without invoking unexpectedly large millimeter-sized grains.
Spectroscopic observations of disintegrating comet C/2019 Y4 (ATLAS) classify it as a typical Oort cloud comet with less dust, where porous dust accounts for its slightly red reflectivity gradient of ~5% per 1000 Å.
