The Effect of Weak Cosmic-ray Heating Events on the Desorption of H2

The typical amount of molecular hydrogen (H _2 ) in interstellar ices is not known, but significant freeze-out of H _2 on dust grains is not expected. However, chemical models ubiquitously predict large amounts of H _2 freeze-out in dense cloud conditions, and specialized treatments are needed to co...
