Theneowise-Discovered Comet Population and the Co + Co₂production Rates

The 163 comets observed during the WISE / NEOWISE prime mission represent the largest infrared survey to date of comets, providing constraints on dust, nucleus size, and CO + CO 2 production. We present detailed analyses of the WISE / NEOWISE comet discoveries, and discuss observations of the active comets showing 4.6 μ m band excess. We find a possible relation between dust and CO + CO 2 production, as well as possible differences in the sizes of long and short period comet nuclei.
