Incorrect/Incomplete answer (again) to this particular question. (I
have attached the wrong answer that keeps being posted by the same
person).
Question:
Wrong answer:
2. Non-Resonant Reaction Rates and the Lower Mass Main Sequence Low mass (< Mo) stars consume hydrogen mostly via the proton-proton cycles. -0.5 (a) Use the energy generation rate of equation 6.76 in HKT to find (roughly) the central temperature required so that the energy production rate matches the loss for the Sun. (b) For stars less massive than the Sun, use the earlier derived luminosity L M5.5 R-O (all in solar units) to find the radius, central temperature and effective temperature as a function of mass for stars on the Main Sequence. What are the main sequence lifetimes as a function of mass? (c) How sensitive is the nuclear energy generation rate to the central temperature? (i.e. what is a in εα T8) (d) What is the lowest mass star that you can construct which burns hydrogen in steady state? (Don't forget degeneracy).
