(c) Explain why convective instability occurs in hydrogen ionization zones within stars. (d) Estimate the main sequence lifetime of a 5 Mo star. Explain carefully all the assump- tions you have made in the calculation. The effective temperature of such a star is approximately 17000 K and its radius 2.7 times that of the Sun. The mass of a He nucleus is 6.6465 x 10-27 kg.
