Proposed Importance of HOCO Chemistry: Inefficient Formation of CO2 from CO and OH Reactions on Ice Dust

The Astrophysical Journal
With the advent of JWST ice observations, dedicated studies on the formation reactions of detected molecules are becoming increasingly important. One of the most interesting molecules in interstellar ice is CO _2 .

Detection of CO2 ice in the planetary nebula NGC 6302

Astronomy & Astrophysics
Using JWST/MIRI observations, we report the detection of CO2 ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile molecular species and ices due to intense UV irradiation.

Frozen in time: the chemistry of polar ice cores

, 2007
Predicting the future of our Earth and its climate requires models that contain good representations of the key processes that might take place. Our only way to determine what these processes are, and to test the models, is to look at the past. Numerous

Molecular Level Interpretation of Vibrational Spectra of Ordered Ice Phases

, 2018
We build on results from our previous investigation into ice Ih using a combination of classical many-body molecular dynamics (MB-MD) and normal mode (NM) calculations to obtain molecular level information on the spectroscopic signatures ...
