[2508.19339] The Binding Energies of Atoms on Amorphous Silicate Dust: A Computational Study Skip to main content We gratefully acknowledge support from the Simons Foundation, member institutions , and all contributors.
We used the Geometries, Frequencies, and Non-covalent Interactions Tight Binding (GFN1-xTB) method to compute the binding energies.
The probability distribution of binding energies for each element except Ca is statistically consistent with a log-normal distribution.
These binding energies on silicate dust grains, estimated from first principles for the first time, provide invaluable input to models of dust evolution and dust-catalyzed chemical reactions in the interstellar medium.
