Machine Learning Exploration Of Binding Energy Distributions Of H2O At Astrochemically Relevant Dust Grain Surfaces
Binding energies (BEs) of adsorbates on interstellar dust grains critically control adsorption, desorption, diffusion, and surface reactivity, and therefore strongly influence astrochemical models of star- and planet-forming regions.
