Query: Heat expansion of star-like cosmic objects induced by the cosmological
  expansion   The heat expansion of a star-like cosmic object, induced by the cosmological
bremsheat production within a moving body, that was predicted by the Projective
Unified field Theoriy of the author, is approximately treated. The difference
to planet-like bodies investigated previously arises from another material
constitution. The exponential-like expansion law is applied to a model with
numerical values of the Sun. The results are not in contradiction to empirical
facts.
