Scientific paper

The abundance of oxygen in planetaries is examined for three different physical descriptions of the density and temperature structure. A comparison of these abundances with expectations derived from an energy-balance perspective leads to the conclusion that, for the models considered here, the most satisfactory oxygen abundance is derived by assuming a uniform density and temperature for a planetary.
