Detailed Description

A Star (Star1,Star2,Star3,.

..) cannot be a StelObject. The additional overhead of having a dynamic type would simply be too much. Therefore the StarWrapper is needed when returning Stars as StelObjects, e.g. for searching, and for constellations. The StarWrapper is destroyed when it is not needed anymore, by utilizing reference counting and boost::intrusive_ptr. So there is no chance that more than a few hundreds of StarWrappers are alive simultanousely. Another reason for having the StarWrapper is to encapsulate the differences between the different kinds of Stars (Star1,Star2,Star3).
