Scientific paper

The energetics of the mechanism believed to be responsible for the long-lived luminosity of certain meteor trains is examined. The proposed mechanism involves the store of recombination energy of free atmospheric oxygen with sodium atoms continuously catalyzing the transformation of atomic oxygen to molecular oxygen by NaO formation, so that the dissociation energy of O2 is converted into sodium light with the aid of the atmospheric species O3 and O2. The complete sequence of reactions is outlined, and a model is discussed which shows how a meteor train would be formed by this mechanism. Emission rates are calculated on the basis of this model and are compared with observed train luminosities.
