Abstract:
This paper presents JHKL'M photometry of a new sample of OH/IR stars.
These data are merged with similar observations collected in the
literature in order to constitute a data base of near-infrared photometry
for 400 OH/IR stars. After removing from this sample the objects that are
unlikely to be AGB stars, we obtain a sequence of average OH/IR stars
with increasing values of the colour index K-L'. A simple model of a star
surrounded by a circumstellar shell is constructed in order to derive
basic parameters such as luminosity, radius, stellar temperature, optical
depth of the dust shell and mass loss rate. These parameters are found
to vary smoothly along the sequence of OH/IR stars, and the K-L' colour is
shown to describe almost completely the basic physical parameters of an
OH/IR star. The metallicity affects the OH-peak separation, but does not
play an important role in the definition of the other properties.
