The determinations of the age of the oldest objects in the universe, giving a lower limit of the age of the universe itself, are of great interest in astrophysics and cosmology. With the detection of the long-lived isotopes of thorium and uranium in a single star, their application as cosmochronometers has become possible. With network calculations, the production of Th and U can be studied for different input of the underlying mass model and the astrophysical environment...
