dc.description.abstractEnObservation of CO2 in exoplanet atmospheres is one of the major science themes for James Webb Space Telescope (JWST). CO2 cannot be observed in the gas phase through rotational transitions in the far-infrared or submillimeter range due to its lack of permanent dipole moment. It has to be observed through its vibrational transitions at near- and mid-infrared wavelengths. We will show how observation of protonated form of CO2 in a solar-type protostar help us to better understand the overall temperature structure, ionization structure, H2O and CO2 snow lines, and overall C/O ratio. Implications of our study to the chemistry of CO2 ices using JWST-MIRI and NIRSpec will be discussed as well.
