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.
