### Understanding Stellar Evolution: Why Do Massive Stars Evolve Faster? #### Explain why massive stars evolve faster? Massive stars evolve at a more expedited rate in comparison to their less massive counterparts. This phenomenon primarily occurs due to the higher core temperatures in massive stars. ### Key Points: 1. **Higher Core Temperatures**: The immense gravitational forces in massive stars lead to extremely high core temperatures. These conditions accelerate the nuclear fusion processes. 2. **Quicker Hydrogen Fusion**: In massive stars, hydrogen is consumed at an accelerated pace due to the higher temperatures and pressures. This rapid fusion leads to a faster consumption of the star's core fuel reserves. 3. **Shorter Lifespan**: Due to the rapid fusion processes, massive stars exhaust their hydrogen fuel much quicker, leading to shorter lifespans despite their larger sizes. Understanding the lifecycle and evolution of massive stars is crucial for comprehending various cosmic phenomena, such as supernovae and the formation of black holes.
