Wright, and the WISE, NEOWISE Teams arXiv: 1509.08446 ยท 2015-10-09 ## TL;DR This study analyzes 163 comets observed by NEOWISE, providing insights into their dust, nucleus sizes, and CO+CO2 production, and explores relationships between these properties. ## Contribution It offers the largest infrared survey of comets to date, revealing correlations between dust and gas production and differences in nucleus sizes among comet types. ## Key findings - Possible relation between dust and CO+CO2 production. - Differences in nucleus sizes of long and short period comets. - Comprehensive infrared data on comet properties. ## Abstract The 163 comets observed during the WISE/NEOWISE prime mission represent the largest infrared survey to date of comets, providing constraints on dust, nucleus sizes, and CO+CO2 production. We present detailed analyses of the WISE/NEOWISE comet discoveries, and discuss observations of the active comets showing 4.6 $\mu$m band excess. We find a possible relation between dust and CO+CO2 production, as well as possible differences in the sizes of long and short period comet nuclei. --- Source: https://tomesphere.com/paper/1509.08446
