2. [6 pts] The lower limit to the main sequence occurs when the core temperature of a star is no longer sufficient to fuse hydrogen into helium. We have previously estimated the core temperature for a star with mass M and radius R and the temperature required for p?p fusion via quantum tunneling as Tcore ??kRGMmp?? and Tfusion ??3kh24Z12?Z22?e4?? Use these and the mass-radius relationship for main sequence stars to estimate the lowest mass star capable of fusion. Give your answer in units of M??.
