# Estimation of the physical parameters of planets and stars in the gravitational equilibrium model

@article{Fedosin2016EstimationOT, title={Estimation of the physical parameters of planets and stars in the gravitational equilibrium model}, author={Sergey G. Fedosin}, journal={Canadian Journal of Physics}, year={2016}, volume={94}, pages={370-379} }

The motion equations of matter in a gravitational field, acceleration field, pressure field, and other fields are considered based on the field theory. This enables us to derive simple formulas in the framework of the gravitational equilibrium model, which allow us to estimate the physical parameters of cosmic bodies. The acceleration field coefficient, η, and the pressure field coefficient, σ, are a function of the state of matter, and their sum is close in magnitude to the gravitational… Expand
