(a) Calculate the Jeans mass for gas with a temperature of 30K, a density of 7.2 x10-6 g/cm, and a composition of 90% by mass H and 10% He. (b) A proto-star eventually forms from this cloud and has a radius of 75 R. What is the approximate mass of this protostar? (c) Draw on a Hertzsprung Russell diagram, the path of this protostar as it travels along the Hayashii track and eventually settles onto the ZAMS, labelling the forbidden region and rough location/shape of the ZAMS for a range of stellar masses (Note: numbers are not required on the axes). (d) With reference to the interior structure and V ad, explain why the star starts on the Hayashi track and then moves onto the ZAMS. (d) Draw and label the interior structure of the star on the Hayashi track and on the ZAMS. (e) Draw the remaining stages of the star's evolution on the Hertzsprung Russell diagram up to and including the AGB, labelling the following stages: sub-giant branch, red-giant branch, He flash, horizontal branch and AGB.
