Dynamical frequency of a uniform-density star
= Dynamical frequency of a uniform-density star
{title2=$\omega_d$}
The frequency $\omega_d=(GM/R^3)^{1/2}=(4\pi G\rho/3)^{1/2}$ measures the inverse gravitational timescale of a uniform-density sphere. It is the natural normalization for <uniform-density stellar oscillation> and the linear restoring or destabilizing accelerations.
