SUMMARY
The discussion centers on deriving the enclosed mass M(r) in the Hernquist model, which describes mass distribution in spheroids. The density function is given by ρ(r) = M(total)*a / 2πr(a+r)^3, where M(total) represents the total mass and 'a' is a constant with dimensions of length. The solution involves integrating the density function to find the relationship between mass density and enclosed mass. The integral approach is essential for solving this problem effectively.
