Description
Kristen Darnell and colleagues add ion chemistry inside ice mantles to models of star-forming regions in 2026 work. Chemistry on dust grains is thought to help build molecules that precede life, yet reactions among ions buried in ice remain little studied. The team modeled pure oxygen ice lit by ultraviolet photons, with bulk ion reactions built into the network.
Comparing their runs with earlier data suggested that ion-neutral and ion-ion reactions shape ice chemistry in a major way. Ignoring those buried ions may leave models missing key steps in how interstellar ice evolves. The methods also extend to other forms of ionizing radiation found in space.
