J
Jeans Length
Below λ_J pressure waves cross the region faster than it can fall in, and it rings instead of collapsing; above it, gravity wins. The Jeans mass of Part 2.9 is the mass of a sphere of diameter λ_J, M_J = (π/6)·ρ·λ_J³, which gives its form (π^(5/2)/6)·σ³/(G^(3/2)·ρ^(1/2)).
λ_J = σ · √(π / (G · ρ))
