New Gemini and JWST data show 450P/LONEOS has a 1.8 km nucleus, CO2 gas production of ~7e24 molec/s, water ice absorption, and activity consistent with CO2 release from crystallizing amorphous ice.
ALMA survey detects H2CO in 45% of 20 disks and finds strong correlations of line luminosity with disk size, mass, and stellar luminosity, suggesting grain-surface formation.
