A pure geometric primitive model for a main sequence star

Wanas, M.I. ; Samah Abd El-Aziz Saber Ammar 


Abstract


he field equations, of a pure geometric field theory, are solved in the case of spherical symmetry. The solution obtained is shown to be an interior one with pure geometric material-energy tensor. This solution is obtained, assuming a perfect fluid filling a spherical configuration. An equation of state is obtained from, and not imposed on, the model. If the model is considered to represent a main sequence star, it gives rise to a corona and a radiation zone. Possibility of existence of a convection zone is discussed. Comparison with the parameters of the Sun is given.
