(a) Estimate the Eddington luminosity of a 0.072 M, star and compare your answer to the
main-sequence luminosity given in Problem 21. Assume k = 0.001 m² kg¯'. Is radia-
tion pressure likely to be significant in the stability of a low-mass main-sequence star?
(b) If a 120 Mo star forms with log1o T. = 4.727 and log1o(L/Lo) = 6.252, estimate its
Eddington luminosity. Compare your answer with the actual luminosity of the star.
