The theory of figures of Clairaut with focus on the gravitational rigidity modulus: inequalities and an improvement in the Darwin-Radau equation

Clodoaldo Grotta Ragazzo

This paper contains a review of Clairaut's theory with focus on the determination of a gravitational rigidity modulus $\gamma$ defined as $\left(\frac{C-I_o}{I_o}\right)γ=\frac{2}{3}Ω^2…
