<N. W. Evans> developed analytic models of <galaxies> and dark haloes with <J. An>. Their <hypervirial distribution function> has the form $f\propto L^{p-2}\mathcal E^{(3p+1)/2}$, where $L$ is specific <angular momentum> and $\mathcal E$ is relative binding <energy>.<Hypervirial Models of Stellar Systems by N. W. Evans and J. An>[Abstract and section 2.2: phase-space distribution and moments]{ref}
The resulting <hypervirial models> connect an adjustable central density cusp to an explicit dynamical population, extending useful features of the <Plummer model> beyond its finite-density core.
