Question

Quizplus · Accepted Answer

A higher mass protostar will develop into a hotter and bluer main sequence star than a lower mass protostar. This is because higher mass stars have higher core temperatures and pressures, which leads to faster fusion reactions and a higher rate of energy production. As a result, they emit more radiation, including more ultraviolet radiation that ionizes nearby gas, and more ionizing photons that can trigger additional star formation. This also means that high mass stars evolve more quickly and have shorter lifetimes than low mass stars. Therefore, the evolutionary track of a high mass star on the Hertzsprung-Russell diagram will be located above and to the left of that of a low mass star, and will not intersect with it. A high mass protostar will have a shorter lifespan than a lower mass protostar, as it will exhaust its fuel at a faster rate. As a result, the high mass protostar will have a higher surface temperature and luminosity, causing it to form into a bluer star on the main sequence. The evolutionary tracks of high and low mass stars do not cross, as they follow different paths of development.
