Scientific paper

The statistical properties of OH/IR stars are studied and related to current theories of stellar evolution on the Aysymptotic Giant Branch and the evolutionary role of mass loss through a very dense stellar wind. The physical parameters that determine the OH luminosity are investigated and a relation is found between the luminosity and the size of the circumstellar shell which leads to a quantitative expression for luminosity as a function of mass loss rate. The evolutionary time scale of mass loss is derived from the observed distribution of OH luminosities, and the results are combined with the Reimers relation to derive an expression for the evolution of mass loss in terms of the basic stellar parameters incorporating the 'superwind' phase. The dependence of the mass loss rate on the mass of the stellar envelope is demonstrated. A quantitative relation between the expansion velocity and the main sequence mass of a star is obtained, leading to the derivation of stellar parameters based on the OH observations.
