Unformatted text preview: main sequence stars. However, stars of about one solar mass or less havent had time to turn into red giants, so a steady state is not established and we these stars presently only contribute radiation in the main-sequence phase. Problem 2: The rotational energy of pulsars Angular momentum conservation: n ' R 2 R 2 n ' 4 10 10 The period P n = 2 / n ' 1 . 6 10-10 -1 E = 1 2 I 2 = 1 2 P E n ' 4 10 10 E The energy comes from the gravitational potential energy....
