Abstract
We consider a generalization of the interior Schwarzschild solution that we match to the exterior one to build global C 1 models that can have arbitrary large mass, or density, with arbitrary size. This is possible because of a new insight into the problem of localizing the center of symmetry of the models and the use of principal transformations to understand the structure of space.
