Chemistry in Protostellar regions: New implications for JWST MIRI/NIRSpec

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