Repeat Problem 10.27 using the same mass but a different composition; assume X=0.7, Y=0.290, Z=0.010.
(a) For a given mass, which model (Z=0.008 or Z=0.010) has the higher central temperature? the greater central density?
(b) Referring to the appropriate stellar structure equations and constitutive relations, explain your results in part (a).
(c) Which model has the largest energy generation rate at the center? Why?
(d) How do you account for the differences in effective temperature and luminosity between your two models?
