6) A typical "neutron star" of $10^{57}$ particles at a temperature of 5 MeV and enclosed into a sphere of 100 km radius corresponds to $(λ N, λ^{- 4 / 3} β, λ^{- 1 / 3} R)$ with $N = 1$ , $β = 60 ℏ^{2} κ^{- 2} m_{N}^{- 5}$ , $R = 29 ℏ^{2} κ^{- 1} m_{N}^{- 1}$ and $λ = 10^{57}$ . Since $N$ , $S$ and $R$ are of order unity (if measured in their natural units) and since $λ = 10^{57}$ is sufficiently large, we will describe the above "neutron star" by the limit $λ \to \infty$ . For $N = 1057$ , $β = {(5 M e V)}^{- 1}$ and $R = 100$ km we would have reached the same accuracy for $λ = 1$ .
