Question

Quizplus · Accepted Answer

More massive stars have more gravitational potential energy, and therefore more pressure and temperature in their cores. This leads to a higher rate of fusion, which in turn produces more energy and makes the star more luminous. Additionally, larger stars have a larger size, which makes them cooler on the surface and hence they appear redder, while their core is hotter and bluer due to higher temperatures. This difference in temperature between the surface and the core makes them pulsate slower. So, more massive stars are more luminous and larger than less massive stars, and they pulsate slower.
