1. In this question, you may assume that the core temperature in the Sun is T=15x10$K. L Bolatively low mass stars (MsMojhrave- homologyshow that the contral temperature in such stars scales as b) For hydrogen burning via the p-p chain to ignite, the temperature at the centre of the star must be larger than 4x10$K. Calculate the minimum mass (in Solar masses) a star must have to ignite hydrogen. How does this compare to the mass of brown dwarfs?
