Fizzy water ice in space: CO$_2$ adsorption, binding energies and its fate in a protoplanetary disk

Alicja Bulik, A. Rimola, C. Ceccarelli, E. Mates-Torres, K. Furuya, P. Ugliengo, V. Bariosco

A spread in CO2 binding energies on water ice extends the gaseous reservoir farther in protoplanetary disks than a single value predicts.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We confirm that the use of BE distribution to model the gas and ice fractionation in a protoplanetary disk causes the gas fraction to be significantly more extended.

C2weakest assumption

The amorphous water ice grain model combined with the ONIOM scheme produces binding energies that accurately represent real interstellar conditions and adsorption sites.

C3one line summary

CO2 binding energies on water ice follow a bimodal Gaussian distribution that significantly extends the gaseous CO2 fraction in protoplanetary disks.
