The Different Types of Red Dwarfs

The way the heat gets mixed around in their core is a little bit different than in our star. A red dwarf mixes in a different way because there's not so much radiation produced at its core, so there tends to be more convection of the plasma. It's another reason why these red dwarfs last a really long time. Some calculations suggest that a small star like 10% the mass of our sun could last for 10 trillion years.
