Tianwen-1 provided the first out-of-plane imaging of 3I/ATLAS, indicating large dust grains (hundreds of micrometers) ejected at 3-10 m/s with steady-state outflow and a mass loss rate of about 1000 kg/s.
Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
Radiative transfer modeling of protostellar ices shows absorption originates mainly from 1000-2000 au at the cavity-envelope transition, with apparent CO2/H2O and CO/H2O ratios potentially underestimated due to line-of-sight effects.
