Uniformly rotating barotropic star
= Uniformly rotating barotropic star

In a connected inviscid uniformly rotating <barotropic fluid>, momentum balance makes the displayed sum constant. The <pressure> term is the <barotropic enthalpy function>. Perturbations experience <Coriolis acceleration>, and their rotating-frame frequency depends on the chosen exponential sign convention.
