WebAnswer (1 of 8): The general formula for calculating the mass of a sphere is the integral of the mass density (mass per unit volume) over the volume of the sphere M = \int d^3x … WebThe Plummer model or Plummer sphere is a density law that was first used by H. C. Plummer to fit observations of globular clusters. [1] It is now often used as toy model in N-body simulations of stellar systems. Description of the model [ edit] The density law of a Plummer model The Plummer 3-dimensional density profile is given by
