r = | radius |
P = | pressure at r |
G = | gravitational constant |
M = | mass of material within r |
_{} = | density at r |
L = | luminosity at r (rate of energy flow across sphere of radius r) |
= | energy release per unit mass per unit time |
T = | temperature at r |
= | opacity at r |
a = | radiation density constant |
c = | speed of light |
P = P (_{}, T, composition) | the equation of state |
= (_{}, T, composition) | |
= (_{}, T, composition) |
