JWST nebular spectra detect cooling ~400 K carbonaceous dust emission in normal SN Ia 2023qov at +276 and +363 days, modeled as pre-existing circumstellar dust with mass ~10^{-4} M_sun located within ~1 light year.

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.
Triaxial gravitational fields of small solar system bodies stabilize narrow rings against solar radiation pressure loss, allowing sub-mm particles to persist.
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.
NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.

Variable dust emission by WC type Wolf-Rayet stars observed in the NEOWISE-R survey
NEOWISE-R data identifies ten new non-variable dust makers among WC stars (including three early subtypes), six new episodic dust makers, and revises the dust formation period of HD 36402 to 5.1 years.
