The energy generation rate in the p-p chain and CNO cycle both scale linearly with this quantity.
The energy generation rate in the p-p chain and CNO cycle both scale linearly with this quantity. The condition for hydrostatic equilibrium in stars is that the derivative of pressure with respect to radius equals this quantity times G M over r squared. The linear stellar model assumes that this quantity decreases linearly from the center of a star to the edge and finds that its "central" value is equal to three M over pi r cubed. Polytropes model star pressure as a constant times this quantity to the n plus one over n, where n is the polytropic index. Neutron stars' extremely high value for this quantity is around that of an atomic nucleus and more than 10 to the 14 times that of the sun. For 10 points, name this quantity which, if constant throughout a star, can be given by mass over volume.
