... Due Nov. 18, by 5 pm, to the Astro 320 drop box. Problem 1: a) C & O, problem 11.2a. The Sun’s luminosity is 3.8 × 1026 W, or J/s. That translates, via E = mc2 , to m = E/c2 = 3.8 × 1026 /(3 × 108 )2 = 4 × 109 kg/s. Per year, that’s 3.16 × 107 ∗ 4 × 109 = 1.26 × 1017 kg/year, or 6.3 × 10−14 M /year ...
