A Pure Geometric Primitive Model For a Main Sequence Star |
The 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. |
