WebJan 11, 1997 · Comment: This equation only holds true for stars in which the central pressure is determined by the ideal gas equation. Examples: (1) Star A is twice as … WebSolving for n in equation (1), we see that the number density is related to the mass density by. n = r / m m H. so the equation of state becomes. P = r kT / m mH . (2) Finally, solving for T and using our estimate of central pressure above, we get for the central temperature. T c = Pc m mH / k = 1.44 x 10 7 K. black stitched shirts https://alexeykaretnikov.com
