* Gravity: High mass stars have a much stronger gravitational pull. This intense gravity compresses the core to extremely high densities and temperatures.
* Nuclear Fusion: The extreme conditions in the core of high mass stars allow for much faster nuclear fusion reactions. Fusion is the process where lighter elements fuse together to form heavier elements, releasing immense amounts of energy.
* Energy Output: The faster fusion rate in high mass stars means they produce significantly more energy, making them much brighter and hotter than low mass stars.
Here's a simplified analogy:
Imagine you have two bonfires. One is small and has a slow-burning fire. The other is massive with a blazing fire. The larger bonfire consumes fuel much faster and produces more heat and light, just like a high mass star.
In summary:
* High mass stars: Burn fuel (hydrogen) rapidly due to strong gravity and high core temperatures, resulting in a much shorter lifespan (millions of years).
* Low mass stars: Burn fuel slowly due to weaker gravity and lower core temperatures, resulting in a much longer lifespan (billions of years).
