CO+CO₂ Production in Comet C/2020 F3 (NEOWISE)

Studying the CO+CO2 production rate in comets is important to understand species that are responsible forsubsurface sublimation at locations farther than 2.5 AU from the Sun (Meech & Svoreň 2004). A full inventory of volatile loss provides constraints on the evolution of these icy bodies. Here, we present measurements of the CO+CO2 emission in Comet C/2020 F3, a long-period comet discovered during the NEOWISE mission and space telescope (A. Mainzer et al., 2011). We use the NEOWISE data in two channels with central wavelengths at 3.4 μm and 4.6 μm to measure the CO+CO2 production. The main purpose of this work is not only to understand Comet C/2020 F3 in terms of the major volatiles but primarily to migrate the existing numerical models written in IDL for estimating the CO+CO2 production rates (Bauer et al., 2021) into Python libraries, which will be beneficial to build the pipeline contributing to analyzing CO+CO2 extraction routines for the NEO surveyor.
