The Unreasonable Effectiveness of the nΣv Approximation
In kinetic theory, the classic n Σ v approach calculates the rate of particle interactions from local quantities: the number density of particles n , the cross section Σ, and the average relative speed v . In stellar dynamics, this formula is often applied to problems in collisional (i.e., dense) en...
